Description of problem:
After upgrading from RedHat 9, the MASQERADE with IPCHAINS freezes OS
when I use it as an internet gateway.
This is from memory because I lost what I had typed in the "standard
I put in the approprate commands for forwarding in:
/etc/sysconfig/ipchains MASQ and fowarding is properly set.
/etc/sysconfig/network GATEWAY eq 192.168.1.1
/etc/sysctl.conf = allow IP 4 forwarding = 1
eth0=connected directly to internet 192.168.1.5
eth1=connected to internal lan and acts as gateway address
Just email me for more details.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Made the above config changes under RH9, used it for months
without problems (routing was stable), then upgraded to Fedora Core 1
2. Replicated this on another machine with completely different
hardware, and got the same results.
Actual Results: The system freezes, only a cold reboot works.
CTRL / ALT / DELETE does not work.
Expected Results: I expected it to route as it did under 7.3, 8.0,
and 9.0 RedHat.
Please email me for more details.
The "ipchains" command, of which this bugzilla module is for, is
just the command that sends ipchains rules to the kernel. It does
contain any code which can lock up a machine whatsoever.
Reassigning to the kernel.
Did this ever get fixed?
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
