Description of problem: s-c-firewall has this nice Masquerading section in it which creates the NAT rules in the PREROUTING and POSTROUTING chains, and it even helpfully turns on IPv4 Forwarding for you. Unfortunately, it doesn't remove the default iptables rule that blocks all traffic in the FORWARD chain. This kinda makes the whole "easy to configure masquerading" functionality pointless. Version-Release number of selected component (if applicable): 1.0.12-3.1.fc8 How reproducible: always Steps to Reproduce: 1. Enable the checkbox on an interface in the Masquerading section. 2. Apply. 3. Note that no packets are allowed to be forwarded. Actual results: -A FORWARD -j REJECT --reject-with icmp-host-prohibited Expected results: Remove the FORWARD rule that REJECTs all packets.
Please have a look at system-config-firewall-1.0.12-4.fc8 in F-8 testing.
system-config-firewall-1.0.12-4.fc8 has been pushed to the Fedora 8 stable repository. If problems still persist, please make note of it in this bug report.
