A Slip-Networked Amiga Ethernet Gateway

AmiTCP 4.2 Setup – SLIP connection

A1200 Side

Install AmiTCP 4.2, run the configuration and make sure you create a login (usually does that automatically and asks you for a new password).

A quick guide to a part of the initial installation/config should go like this:

Proceed into the Installation

Note: On initial Installations it may first prompt you to create a username/login and ask you to set a password. Just follow the onscreen instructions for that.

Select: Normal Configuation
Select: SLIP/CSLIP
Select: rhslip
Enter the IP: 192.168.0.1
Enter Netmask: 255.255.255.0
Correct? Select: Yes
Select: serial.device
Unit: 0
Baud: 38400
MTU: 1006
Disable (uncheck) EOF and Hardware Handshaking
Correct? Select: Yes
Enter Default Gateway: 192.168.0.2
Enter Hostname: A1200
Enter Domain: pokelan.nl
Enter Aliases: Skip by hitting the proceed button
Serv/Inetd programs? Select: Yes
Done

On the A1200, we don’t actually specify any Ethernet device in the config, thats because we are going to plumb in the cnet device later on…manually!

A500+ Side

Proceed into the Installation
On initial Installations it may first prompt you to create a username/login and ask you to set a password. Just follow the onscreen instructions for that.
The configuration process – Select:
Select: Normal Configuation
Select: SLIP/CSLIP
Select: rhslip
Enter the IP: 192.168.0.2
Enter Netmask: 255.255.255.0
Correct? Select: Yes
Select: serial.device
Unit: 0
Baud: 38400
MTU: 1006
Disable (uncheck) EOF and Hardware Handshaking
Correct? Select: Yes
Enter Default Gateway: 192.168.0.1
Enter Hostname: A500
Enter Domain: pokelan.nl
Enter Aliases: Skip by hitting the proceed button
Serv/Inetd programs? Select: Yes
Done.

AmiTCP/CNet.device & Routing Setup

The A1200 Side

Edit the configurations to reflect the settings below AFTER you have done the install. The reason being is that there are important files copied and password files setup during install which may overwrite the files we want to change…
First, you will need to download Cnet.device (from Aminet) and copy it into your DEVS:Networks/ directory.

Below are a list of files which will need editing to configure the system, although most of them will be ready-to-go from the initial installation, it is wise to read through them ALL and edit when necessary.

rhslip0.config

# $Id: rhslip0.config,v 1.1 1993/08/17 00:00:00 rhialto Exp $
#
# This file is the configuration file for the SANA-II SLIP
# driver.  It only contains one config line (aside from
# the comments).  The format of the line (in ReadArgs()
# style) is:
#
# SERNAME/A,SERUNIT/A/N,SERBAUD/A/N,IPSTR/A,CD=CARRIERDETECT/S,7WIRE/S
#
# SERNAME - The name of the serial device to use.
#
# SERUNIT - The unit number for the serial device.
#
# SERBAUD - The baud rate to use with the serial device.
#
# IPSTR    - The IP address of the SLIP Device
#
# CD=CARRIERDETECT - If specified, causes the slip.device to pay attention
#                    to the status of the carrier detect line.  If this isn't
#          specified, slip.device ignores the CD signal.
#
# 7WIRE   - If specified, causes slip.device to use seven wire handshaking
#      with the modem (strongly recommended for high baud rates).
# 
# This is the file which tells rhslip.device which serial driver to use.
# in our case, this is serial.device.
# Those smart alecs out there who may try and use the BaudBandit.device to increase
# the byte thruput may be dissapointed as I couldnt get it to work... Let me know if you
# manage.
# One IMPORTANT point worth mentioning is this file should reside in:
# ENVARC:Sana2/rhslip0.config
# The ENVARC: is available via CLI as ENVARC: or in SYS:Prefs/Env-Archive
# 
# The IP address 1.1.1.2 is just any IP, since its on both ends of the slip i'm
# not too sure about it's importance as it hasn't affected operations.
# (Whether it really interferes with the real 1.1.1.0 network is something i dont know)
# Just leave it like this for the time being!
serial.device 0 38400 1.1.1.2

; This file is the startnet which resides in AmiTCP:bin/startnet
; This is for the Amiga doing the SLIP-Ethernet routing. In my
; case it is the A1200. This is almost identical to the A500's SLIP setup, except for the
; swapped around IP address and default gateway address. There is no Ethernet setup in this file.
; that is all sorted out in the user-startnet and interfaces files.
; 
; Set the IP address of the slip0 interface as shown:
.def IP    192.168.0.1
;
; Give your machine a name! Even if you don't have a domain, you must specify a dummy one.
; in my case I chose pokelan.nl ;P 
.def HN    "a1200.pokelan.nl"
;
; Leave the DEST parameter empty...
.def DEST  
;
; Set your netmask to this:
.def MASK  255.255.255.0
; IP address of the default gateway - Since you are setting this machine as a SLIP connection
; the only other destination you can have is the machine at the other end! in my case this 
; will be my A1200's SLIP IP.
.def GW    192.168.0.2
;
; Default login name - Set this to something you set up in the AmiTCP passwd file...
; Its a good idea to use the AmiTCP Installer tool to add a userid before you edit
; this file...
.def USER  red
;
; User's file creation mask - Set this to 022
.def UMASK 022
;
; "SRV" if servers are used. Set it to SRV for now.
.def SRV   SRV
; 
; "BOOTP" if bootstrap protocol is used, since it's now - just leave it blank.
.def BOOTP 
;
; Interface name - VERY important that you get this identical to the one in the 
; AmiTCP:db/interfaces file. Since I have provided that config you might aswell leave
; this set to slip0
.def IFACE slip0
;
; Sana-II device configuration file - Well this is strange, it could be a big but its not...
; you see, even if you define slip0.config here, since we are using rhslip.device it will
; automatically check for rhslip0.config in the ENVARC:Sana2/, so leave this the same as below
; as it is obviously counteracted by rhslip.device
;
.def S2CF  slip0.config
;
; Sana-II device configuration to be stored into the configuration file
; It is weird that this line is here at all! The line below is basically what is contained
; in the ENVARC:Sana2/rhslip0.config file. You can leave this line alone if you wish -
; its not used, I commented it out.
;.def S2OPT "serial.device 0 38400 0.0.0.0 MTU=1006 "

# Ok, the machine you have in the middle of your SLIP and Ethernet device needs to know
# how to get out to the internet. Well. In my case (and in this example's case) the Internet
# Is reachable via a NAT device. A NAT is Explained in the main document, but for clarity it is
# a device which will route your internal network to the outside world, but all connections will
# maquearade as the NAT box's external IP address. Hard to figure? Hmm....
# Look for Network Address Translation on the Internet.
#
# Right, First off, lets tell the ethernet card to assume an identity...
# Give it an IP address with the following ifconfig line:
#
AmiTCP:bin/ifconfig cnet 10.0.0.100 netmask 255.255.255.0 broadcast
10.0.0.255
#
# Now we have that up, we need to tell AmiTCP to send packets to a different Default gateway
# than it wants to... We do this by first DELETING the default route (which is currently
# Assigned to the slip0 device).
#
amitcp:bin/route delete default
#
# Next we tell AmiTCP on which interface to find our NAT box... the NAT box is on the 10.1.0.0
# network, and need to route though the 10.1.0.100 interface.
#
amitcp:bin/route add -host 10.0.0.1 -interface 10.0.0.100
#
#
# Last but not at all least, we need to add a new default route so that all packets not destined
# for the 192.168.1.0 network are routed to the NAT box via the 10.0.0.100 gateway
# Routing can take a while to get the grasp of (it took me a week to get this entire configuration/
# working!) but it will eventually become easier when you know what things go where and why.
#
amitcp:bin/route add default -host 10.0.0.1

# This file is the configuration file for the SANA-II SLIP
# driver.  It only contains one config line (aside from
# the comments).  The format of the line (in ReadArgs()
# style) is:
#
# SERNAME/A,SERUNIT/A/N,SERBAUD/A/N,IPSTR/A,CD=CARRIERDETECT/S,7WIRE/S
#
# SERNAME - The name of the serial device to use.
#
# SERUNIT - The unit number for the serial device.
#
# SERBAUD - The baud rate to use with the serial device.
#
# IPSTR    - The IP address of the SLIP Device
#
# CD=CARRIERDETECT - If specified, causes the slip.device to pay attention
#                    to the status of the carrier detect line.  If this isn't
#          specified, slip.device ignores the CD signal.
#
# 7WIRE   - If specified, causes slip.device to use seven wire handshaking
#      with the modem (strongly recommended for high baud rates).
# 
# This is the file which tells rhslip.device which serial driver to use.
# in our case, this is serial.device.
# Those smart alecs out there who may try and use the BaudBandit.device to increase
# the byte thruput may be dissapointed as I couldnt get it to work... Let me know if you
# manage.
# One IMPORTANT point worth mentioning is this file should reside in:
# ENVARC:Sana2/rhslip0.config
# The ENVARC: is available via CLI as ENVARC: or in SYS:Prefs/Env-Archive
# 
# The IP address 1.1.1.2 is just any IP, since its on both ends of the slip i'm
# not too sure about it's importance as it hasn't affected operations.
# (Whether it really interferes with the real 1.1.1.0 network is something i dont know)
# Just leave it like this for the time being!
serial.device 0 38400 1.1.1.2

services

# This file should only be edited if you are intending to run the webserver in the
# example inetd.conf
# The only line you need to add in this case is:
#
http     80/tcp      arws
#
# I must stress that it is usually very specific to the Http daemon you want to use
# that defines what goes in here... in my example the A500+ is running the arws webserver.rexx

Grey Cell Systems 3400 ethernet 10 base T / v.34 fax modem card

WARNING: The A1200 requires a modification to be done to the Gayle chip before the reset line of the PCMCIA slot will work. Yes! This is a manufacturing bug!

A1200 PCMCIA Reset Fix

The A1200 PCMCIA-port has a bug which causes most PCMCIA-cards not to work after doing a hard reset (cold boot). For PCMCIA modems it is possible to remove the card and insert it again while the power is on. However, removing and re-inserting an ETHERNET card does not work with AmiTCP, as AmiTCP tests via a software check for a card reset!

So, as we gathered – the A1200 does not generate a reset-signal for the PCMCIA port. The problem is “easily” solved by soldering a 10uF capacitor between CC_RESET and and Vcc pins on the Gayle chip. The type of capacitor required is the polarised electrolyte type.

The cathode (-) of the capacitor should be at CC_RESET. CC_RESET can be found on pin 5 of Gayle (U5) and Vcc on R715A (the end which is near Gayle).

A picture ~~(from an external website) of such mod is here: Along with the webpage describing it HERE~~ Sadly looks like that site is now gone. But here is the picture anyway:

WARNING! Although this quite simple in theory – handling a soldering iron can be tricky – make sure you use a LOW wattage iron with a very fine tip, else you may end up de-soldering or shorting other pins on the chip. A useful tool to have handy when soldering is a solder sucker just in case you accidentally solder 2 pins together! If you are not up to doing this then please consult a professional. I take no responsibility for any damages caused by doing anything described in this howto!

N.A.T = Network Address Translation

Though by modern standards you can do this on your home router with ease, back when this how-to was written we were still using ISDN and home brew routers made from multi-interface Unix systems, in my case with a Sun Sparcstation with a Quad Fast Ethernet card behind a cable modem’s own firewall.

Below is for historical reference, you should be able to figure out how to port forward on your home router using many of the guides on the Internet.

You see references to NAT throughout the config files and wonder what it is? Well, simply put – The NAT box is essentially a router – the only difference is that it allows you to route your packets via a NAT box, the NAT box in turn converts your internal IP address to it’s own External IP, makes a record (called a keep state) in memory and then forwards your packet out onto the internet.

This means you can route via the NAT box with your internal LAN IPs.

A lot of DSL/cable routers feature a NAT function, however if you happen to have a spare Sun or Linux machine around, you can set up your own NAT quite easily. In this section I can explain briefly how to set up a NAT using the open source software IPfilter.

Firstly, enable IP_FORWARDING using ndd in order to get your NAT box routing.
Set up your NAT box to function as a router.
Set up a route to tell the NAT box where to find your Amiga 500’s 192.168.x.x network…

REQUIREMENT: You must have a minimum of 2 interfaces. These can be 2 network cards (1 plugs into your LAN, the other a cable modem/DSL).

Setting up NDD is something system specific, it’s best you read the IPfilter HOWTO that is available on the IPfilter website.
On a Solaris box, simply having more than 1 interface makes the machine route. You will naturally have to edit the /etc/defaultrouter file to point to your ISP’s router. For Linux, I don’t know!
In order for your NAT box to be able to reach the network on the other side of your A1200! (the A500)

route add -net 192.168.0.0 -host 10.0.0.100

Since the configuration setup of the Amigas in these documents reference a NAT box with the INTERNAL IP of 10.0.0.1, we shall use that in the following configuration example:

The internal interface (e.g hme0) is the LAN card connecting to your home computers (e.g. the Amiga 1200), and the external interface is the DSL/Cable modem to your ISP (e.g hme1).

First in ipf.conf

This is the rule file for the filtering, we don’t want filtering – so let just do this:

pass in on hme0 all
pass out on hme0 all
pass in on hme1 all
pass out on hme1 all

And the internal loopback interface:

pass in on lo0 all
pass out on lo0 all

Be VERY aware that this opens up your system as a router, when you get things working, check out the manual on how to filter your system!

Next edit ipnat.conf

This file will do the NAT mapping and redirection! (yep, a cool feature!)

Here’s an example:

# For letting Passive FTP work to the outside world…
map hme1 10.0.0.0/32 -> 0/32 portmap tcp/udp 40000:60000
map hme1 0/0 -> 0.0.0.0/32 proxy port ftp ftp/tcp

# This allows NAT to route packets destined for the Internet.
 map hme1 0.0.0.0/0 -> 0/32

# Next map the incoming port 904 map to port 80 of the Amiga500's address
 rdr le0 0.0.0.0/0 port 904 -> 192.168.0.2 port 80
