Where is the best place for iptables help? Is there a mailing list? I've tried the one listed at netfilter.org, but that seems to be Tango Uniform (dead). Setting default policy doesn't seem to work with "REJECT" or "DENY". "ACCEPT" or "DROP" seem to work ok. I try adding rules based on interface device, but when I list the rules in use, I never see the interface listed. EX: This should or may be unnecessary, but this rule is attempting to stop someone outside from masquerading as an internal IP. iptables -A INPUT -p tcp -i eth0 -s 192.168.1.0/24 -j REJECT when I list the rules in effect: (partial display) #iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination REJECT tcp -- 192.168.1.0/24 anywhere reject-with icmp-port-unreachable it is rejecting anything from the non-routable address 192,168.1.X . I I want that to be rejected from eth0, but ok from eth1 . What am I missing? (a clue) Allan -- Psyche-list mailing list Psyche-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/psyche-list
