Hi. Thank you for your bug report.
I can't reproduce this bug. As per http://ipsysctl- tutorial.frozentux.net/ipsysctl-tutorial.html#AEN576 the conf/default will be used also for interfaces that are later loaded. So, try this: # echo 1 > /proc/sys/net/ipv4/conf/default/forwarding # echo 0 > /proc/sys/net/ipv4/conf/eth1/forwarding # to make sure Now let's disable this interface : # ifdown eth1 # ifup eth1 # cat /proc/sys/net/ipv4/conf/eth1/forwarding So it pretty much works as intended. If you don't mind, I'll close this bug since I think it designed to be this way. If you disagree, feel free to re-open it and restart the discussion.
