I am setting up a small CentOS-5.3 host to act as a router. I have the device configured and working. What I am trying to accomplish now is configuring the firewall so as to protect both the router and the LAN.

Thank you for the replies. I have been reading about iptables all weekend and have clarified a number of misconceptions that I had.

I have a few specific questions wrt rp_filter. Is this set anywhere in the startup scripts that ship with CentOS? If so then where? How would one best configure this setting or should it be left off, as I believe that it is by default? Does it make any sense to enable this on the eth0 i/f given that eth0 is the WAN i/f?

Sincerely,
