[lxc-users] No outgoing traffic with bridged network and public IP address from container

Hmm. The old server is also at the same provider and there it is working
without a problem (ubuntu 12.04 and lxc 0.7.5). In addition binding the
22.214.171.124 address to the old server in the same way, the setup works
without a hassle.
Binding the 126.96.36.199 to an aliasing interface (br0:0) on the new
host is working, too...
