Opps. "One" mistake in the note below. It looks like when I run ipchains-restore against a rule like this:
-A input -s 0.0.0.0/0.0.0.0 -d 68.33.8.46/255.255.252.0 6346:6346 -i eth1 -p 6 -y -m 5 The rule as listed by ipchains -L -n is: target prot opt source destination ports - tcp -y---- 0.0.0.0/0 68.33.8.0/22 * -> 6699 So, part of my ip number is missing, too, in the firewall. I guess I don't understand netmasks, but, why, if the end of the number is being chopped off due to the netmask, do they assign this number (68.33.8.46) ?
