My docker server has three uplinks with OSPF for reliability (eth0: 10.0.0.10/24, eth2: 184.108.40.206/24, eth3: 220.127.116.11/24). This done fore redundancy reasons.
This server has loop back/dummy interface with external address (i.e. 10.1.1.1/32) which announces via OSPF.
The problem is that all outgoing connections sources from one of eth* interfaces. The result is I need to specify all three addresses on remote system firewall.
How bind all docker containers to lo/dummy so all my connections are sources from 10.1.1.1?
P.S. here (networking - Change default interface docker container - Server Fault) there is a description how to pin another interface but how to adopt this example to lo.
