just to clarify, what people have responded with is specific or multiple containers running on different ports, for port forwarding purposes, yes? not separate IPs, like for example I have an Odroid H2+ running two separate nodes on two different ports. Although, the Odroid H2+ has two physical ethernet ports, which are both 2.5 gbps. I only have one connected to my switch, which the switch port is only 1 gbps. Although, this isn’t much of an issue as traffic trends have never warranted needing more bandwidth.
If someone wanted to connect multiple RJ45 ports (in my case 2, but as it sounds like the OP mentions 4 ports) and then specify which IP/port each node’s traffic is going through, is there a simple way to do that?
In my personal situation, although the switch’s ports are limited to 1 gbps, it does have two 10 gbps SPF+ uplink ports, which are aggregated to a core switch, so the switch itself has 20 gbps uplink…but then again, my WAN connection is limited to 1 gbps…so the point is very moot.
