linux ip forwarding


Hi penguin lovers

We have a linux ver 9.0 redhat installed with two network cards
. the ip of the card is 172.16.40.1 and 192.168.100.9. this machine is connected to an isdn router whose ip is 192.168.100.1.
I get connected on the nodes which have a class B address to teh linux server running squid proxy. the ip of the proxy is 172.16.40.1 port 3128. my problem is i cannot receive mails in outlook express on the client nodes although i can get connected to the net.
The settings i give normally in the outlook configuration connecting directly via router are
pop3: wmma.sancharnet.in
smtp: smra.sancharnet.in.

This works fine if the client is having the same class ip as the router. The moment u try and download mail via squid it does not work.

Thanks
Walter

Altough I am n00b I think that you should either:
1. Set up a firewall with ip-masquerading and ip-forwarding on you'r server where you can control allowed hosts and so on (instead of proxy)

2. Set up a filter on the server from where you can get you'r mail e.g spambayes (of course this only works if you can get mail from within the server)

3. Weird squid-proxy-configuration!?

Dunno if this is the answers but at least I tryed :-)
I hope you solve it, cheers!

Squid is an HTTP proxy only. You will want to use firewalling on the squid box, specifically ip-masquerading, to get you mail clients to the outside world.
