Backup of 2 workstations behind NAT

[adrian.mate]

Hello,

We have a Veeam Backup & Replication (Community Edition) running on a public IP (with proper firewall rules set in place)
We have to back up 2 workstations that are located in a remote location, with a single internet connection (a single public IP). Those workstations are behind a router/firewall with NAT enabled.
I want configure port forwarding toward the two workstations and open necessary ports for the B&R server.
Is there a way to change the ports used by Veeam (both on the B&R server and agent's side) in order to perform backups / restores on both workstations?

Thank you!
