Heh, systems with single interface are suck. Technically, you can use it
for management and client traffic, but my advice - add more network cards
to system or use other server with two or more interfaces.

If you really can not, than move management IP to bridge and move interface
to br-ex. Note: if you make mistake here, you will lose net access to you
hetzner desktop they call 'server'.
