Hello All, I've been working with giptables firewall and have run into a big issue. Although my script seems to be correct namp is finding ports 25/tcp and 110/tcp open. To start troubleshooting this problem I've commented everything out and stripped down the ruleset to just the default DROP policy. Yet nmap -sT -F -P0 -0 xx.xx.xx.xx still returns 25/tcp and 110/tcp as open! Now I'm starting to think that iptables is broken. I've built iptables with grsecurity-1.9.12 and iptables1.2.8 with a plain vanilla kernel 2.4.22 Is anyone aware of any issues? Dave
