Hi everyone,

I've configured one of my servers as a Home Router using the guide at http://wiki.gentoo.org/wiki/Home_Router.

Everything is up and running.

I just wondered about one thing. Every time I restart the server (and I think even after some emerge updates) I have to re-apply the following configuration:

Code:
root #echo 1 > /proc/sys/net/ipv4/ip_forward


Is there a way to make this configuration more permanent?

Note that I never applied the configuration step directly following in the guide as it was working for me without this. Could it be that this configuration that I did not have to apply:

Code:
root #for f in /proc/sys/net/ipv4/conf/*/rp_filter ; do echo 1 > $f ; done


makes the configuration step just before it permanent as I want?

Thanks,
Nes

This is where you make it permanent:
Quote:
# grep ipv4 /etc/sysctl.conf
net.ipv4.ip_forward = 1
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.all.rp_filter = 1
