Using Coincashew Guide: Topology.json file question

[Alexd1985]

Can the public IP address of the block producing and relay nodes be the same if they are both on a same machine and relay server is running virtually?

Thank you for the reply ADAfrog. The forwarding should be done from the router itself correct? Not the VirtualBox? I ask because I am able to ssh setup the server only when my network is set as “bridge” as oppose to NAT, which prevents port forwarding.

Cheers
