Description Steve Hill 2005-03-10 04:32:10 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0

Description of problem:
/usr/share/doc/initscripts-7.93.5/sysconfig.txt states that the FORWARD_IPV4 option is still valid in /etc/sysconfig/network for turning on IPv4 forwarding.  However, the option does not appear to work and none of the network scripts seem to look for it.

Even worse, the /etc/rc.d/init.d/network script disables IPv4 forwarding on stop, so restarting the network will disable forwarding which was turned on by another means (e.g. set in /etc/sysctl.conf or otherwise).

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

How reproducible:

Steps to Reproduce:
1. Set FORWARD_IPV4=yes
2. Start network
3. Note that forwarding is still disabled despite (1)
4. sysctl -w net.ipv4.ip_forward=1
5. Note that forwarding is now on
6. /etc/rc.d/init.d/network restart
7. Note that forwarding has now been turned off again despite the option (1)

Actual Results:  IPv4 forwarding cannot be turned on by recommended means.  Forcing it on manually by sysctl works but it turned off again upon network restart.

Expected Results:  FORWARD_IPV4=yes option should be honoured as documented.  Infact I think this should probably also be the default if FORWARD_IPV4=no is not specified.
