Description Charles R. Anderson 2007-12-24 23:10:30 UTC
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):

How reproducible:

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.
