Bug 34907 – ip_forward not set to '1' in /etc/init.d/iptables

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Heitzso 2003-12-02 11:12:36 UTC]

I expected the iptables init.d script to set ip_forward in /proc
to '1'.  That would be the appropriate place to set/unset (start/stop).


Reproducible: Always
Steps to Reproduce:
1.emerge kernel/iptables, create firewall w/ NAT using iptables
2./etc/init.d/iptables save
3.next boot iptables set, but the init.d/iptables script didn't set ip_forwarding on

Actual Results:  
NAT not functioning

Expected Results:  
NAT should function.  Actual problem is that ip forwarding not enabled.

Strongly suggest that ip_forward be toggled on/off in /etc/init.d/iptables
script.  That's the fix I'll implement by hand now.  Hard for me to imagine a
more appropriate place to put it.  ???

iptables uses the iptables binaries to save/restore rules

i guess we should add a bit more code to save /proc settings ?

What about /etc/conf.d/iptables 

ENABLE_FORWARDING_IPv4

?

as i can see in changelog, autor has removed it from initscripts but is there any place that i can find it, or for now i need to apply 
echo "1" > /proc/.../ip_forward 
in /etc/conf.d/local.start ???
