Maybe you're using ipchains and you have a rule like this: ipchains -A output -s 0.0.0.0/0 -p tcp -d 0.0.0.0/0 -j DENY That appends that output rule to deny any tcp packets from any ip address to any ipaddress going outbound. You could have used different addresses that would have had the same affect. When you reboot ipchains loses the rules you've applied unless you write a script for it. I can't remember how and why that works but it's in the ipchains how-to. I know there is a gui tool for creating the scripts for ipchains. I read about it today. Can't remember the name. I think it's for gnome. Does anyone else know the name of that thing, url, etc.? I hope this has helped. I've just started using Red Hat 6.1 and I've been setting up an ipchains firewall. It's the only Linux firewall that I know of that drops the rules when you reboot. But it's the only Linux firewall I've had any experience with at all.
