linux box as gateway to internet

[rloc]

linux box is 192.168.0.1 / 255.255.255.000
Win boxes are 192.168.0.xyz /255.255.255.000

The local network works fine via SAMBA and everyone can see everyone else.

Linux is Mandrake 7 kernek 2.4.2

I have made sure that ip forwarding is enabled in /proc/sys/network.

I have made the required changes to rc.local.

I have read the HOWTO's and set up the Win boxes accordingly.

I compiled ipchains support into the 2.4.2 kernel, but I did not compile iptables in.

Should I have done this? Is iptables absolutely required for kernel 2.4.2 or will ipchains still work?

May be irrelevant:

During boot up I get a message /proc/sys/net/ipv4 ip_always_defrag is missing - cannot control ip defragmentation.

If I connect to my ISP using kppp, my kppp stats window displays a "local" and a "remote" address. I can ping the "local" address from any win box but not the remote address.

Ideas please?

thanks

Read and follow the howto for ip masquerading and you should be good to go.

hey download this cool program


pmfirewall

from
www.pmfirewall.com. (http://www.pmfirewall.com.) it is a script that helps you configure IP chains on your computer and also masquareding. Anyone who knows how to read will be able to use it. I had so many problems setting up IP chains on my computer but pmfirewall made it so easy that even a dumb MCSE can install it :)

No disrespect MCSE's :) I know some of you are pretty good
