(Please see attached image) I have a single host with four interfaces (2x 1Gb, 2x 10Gb). eno0 is used for the external nat/route to the upstream firewall and external access via 172.16.27.1. eno1 is not currently used, but *will* be used as a 1Gb guest bridge into a switch (10.0.30.x) enp2s0f0 and f1 are 10gb ports into two different uplink switches (10.0.10.x, 10.0.20.x) What I don't understand how to do in the proxmox environment is to set up route/NAT so that the guest machines in 10.0.x.x (10.x, 20.x, 30.x) will have a gateway interface (10.1, 20.1, 30.1) to: 1. Allow them to communicate between network segments like 10.x <=> 20.x 2. Allow them to communicate uplink like 10.x <=> 10.1 which NAT/route to eno0 (172.16.27.1) Is there a guide anywhere on how to do this kind of thing? I am new to Proxmox, but I have worked in VMWare before and I'm familiar with basic networking. Thanks in advance for any help provided.
