static ip allocation does not work

[kutschkem]

I am calling netns like this:

netns --ip 192.168.124.1/24 --static-ip 192.168.124.123 --bridge br_mathsoverlay

This results in an error

adding route 192.168.123.1 to interface ethc26318 failed: network is unreachable

Removing the static ip removes the error.

This was a problem of the network configuration, I was missing

iptables -I FORWARD -i netns0 -o netns0 -j ACCEPT

The actual issue I had was that I had the bridge already created using a different IP, removing the old bridge resolved the issue.
