After updating linux-image-2.6.26-2-openvz-amd64 from 2.6.26-15lenny3 to 2.6.26-17 and rebooting the HN, /proc/sys/net/ipv4/ip_forward was on 0. Doing

echo 1 > /proc/sys/net/ipv4/ip_forward

fixed it in a hurry, but this should NOT happen.

Hi,

You are posting in the German part of the forum?

@Topic:

Sorry, but I think you should review your /etc/sysctl.conf settings!

This file is usually read at startup and should have the following content -> http://wiki.openvz.org/Quick_installation#sysctl

There you can set your parameter "net.ipv4.ip_forward = 1".

Could it be, that there was an update from your distribution? Are you using a central management software like puppet ore cfenginge which watch for changes on this file?

Regards,

Mario
