> Hello,
> I'm setting up a centos5 router for a friend. It will direct traffic to
> an internal webserver, already in place, as well as run squid proxy. It
> should do nat and have a firewall with iptables. I've set up routers before
> for this purpose but always of the bsd type and using their firewalls. I
> understand the concepts, nat, packet filtering, etc. but i'm not getting
> iptales at all. If anyone is an expert on this i'd appreciate hearing from
> you. I have what are probably basic questions, i've read the docs, but i am
> lost.
> Thanks.
