Hello users, I''m new to this iptables and shorewall and trying understand how it works. Currently I''m using ipchains till I can figure this out. Would rather use iptables. I''m running redhat 7.2 as my server which host my firewall and masq''s for my internal network. The internal network consist of 2 pc''s. My internal network is on eth1 ip of 192.168.0.1/24. The server it self is 192.168.0.1 . I run a www server on the firewall which is on eth0 and ftp, telnet, pop3 and smtp also whixh is only accessable to my internal network. I like to have the internet accessable only to my internal network. I use a pop3 and smtp server from my isp as well. Does anyone have a similiar setup as this and possible to see the configuration so I can figure this one out? Any help is greatly appreciated. John
