Description of problem:
After modyfing roles on a well working firewall-config, we get a problem: the 
forwarding of packets stops.
Returning to previus state and permit all in firewall-config, we still get the 
same forwarding problems. Any idea?

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.modyfing roles of well working firewall-config and apply
2.server don't forwarding any packet
3.returnig to previus state
4.server don't forwarding any packets
5.permit all in firewall-config and apply
6.server donB4t forwarding any packets	

Actual Results:  the configuration of server seems correct,and the 
configuration of firewall-config permit all, and packets forwarding follow 

Expected Results:  the packet forwarding no must stop.

Additional info:

Is a Compaq proliant DL320.

$ cat /proc/sys/net/ipv4/ip_forward

there is nothing wrong with that... should work 
you may try manually: 
# /sbin/service ipchains restart 
after that 
# /sbin/ipchains -L 
should display the same rules as in /etc/sysconfig/ipchains

/sbin/ipchains -L display the same rules as in /etc/sysconfig/ipchains.
But finally i have found a hardware problem in my network, and now server is 
forwarding the packets.
