internet sharing with centOS

[sam_rag]

Dear everyone!

i have been using adsl connection to share internet for whole network using gateway of 192.168.0.101 (for test purpose) with dns address 202.70.64.5
i tried internet browsing with a linux terminas(centOS) with ip 192.168.0.105

I want to use the linux as an internet gateway. so i tried using 2 ethernet cards so i configured them as
eth0: ip address: 192.168.0.105
eth1: ip address: 192.168.28.1
dns address: 202.70.64.5

i wanted to test if i could share the internet from another subnetwork with ip 192.168.28.2 via with gateway configured as 192.168.28.1

now i can ping from the remote computer to both 192.168.0.105 and 192.168.28.1

but internet sharing is not happening

i tried all the steps mentioned by http://www.howtoforge.com/nat_iptables

i wanted to make sure internet sharing happens.. so that i can completely shift to linux for internet sharing..

thanks in advance..

dns address: 202.70.64.5

This address should be configured on one of your ethernet cards then ....
Did you get this address from your ISP?

[sam_rag]

yeah that dns address was supplied by the isp provider
moreover, i believe there are something to do with the iptables and nat
could you please guide me the way?
thanks again

If you want to use your system as a router, you should try a distribution that is tailored for your needs such as IPCop.

there was some conflicting regarding /etc/hosts file.
still more experimenting to do..
messenger etc are working
now i want to learn more..

now i am trying to install squid for proxy..
i downloaded and compiled..
i tried to follow http://www.visolve.com/squid/sqguide.php
but its kinda confusing for a starter like me..
i believe there are easier ways..
i would appreciate if you share your experience
thanks in advance..

Isn't there a Squid package available for CentOS? That would save you from compiling Squid yourself.
