Hi Steve,

It is easy to add a network interface to a VM. Just go in the Proxmox 
web interface on your VM, then Harware menu, then 'Add' button. You can 
there add a new NIC.
It will linked by default to the bridge vmbr0, if you have only this 
one. This brikge is itself linked to the first NIC on your host, say 
eth0. If your IP ranges represent different VLANs, then you have to 
allow different VLAN on the same interface (eth0), and it should be a 
trunk allowing all these VLANs, Another possibility would be to first 
add a new bridge on the host (it also can be done via proxmox web 
interfance), which would be linked for example to the second NIC on your 
host, say eth1.
The two NICs could be in different VLAN...
