Multiple Ip Container

Hi all,

I want to create a container, which sends udp messages to the host from several different ips.
First approach was to create more dockernetworks in bridge mode which all represents one single address address (because the list of ips are predefined).
But I did not find a way to limit a docker network to one special ip address.

so as I crawled through every source I found with no result, I am a little out of option right now.
I hoped someone here had a simular situation, or just an idea how I can deal with this problem.

Thanks guys

Steff
