Greetings. I have a Redhat 7.1 box that acts as a main router/gateway for several segments on my network. It is currently filtering on each interface using ipchains. I would like to migrate these services to iptables to take advantage of the ftp connection tracking module and other stateful matching features. I migrated my ruleset, hacked up the redhat init script to load my script on boot and tried it out on the box. The script loads fine with no errors, and all the clients on each segment work as expected, even active ftp. The problem is, once the script is loaded, even though network-wise everything is fine, i can no longer login at the console on any tty! (ctrl+alt+f2 for example) I enter my username, and hit enter and it just goes into nevernever land. If i log out of the tty that i was in to activate iptables, i'm also unable to log back in on that one either. I have to kill the power to the box and boot single user and switch back to ipchains to restore the box back to production. I have a test box with very similar hardware which is also running rh 7.1 and i'm not able to duplicate the problem on it. Both of these boxes use redhats "up2date" and have all the latest security and bug patches applied. Anyone have any ideas on what might be causing this? I have posted all my rules, my init script, dmesg and iptables version here: http://neotrance.dyndns.org/~schwack/iptables/ ANY help would be GREATLY appreciated. Thanks, Clint
