are the roaming nodes on the same network or different networks. Are they behind NAT?

They are in different network, peer A behind NAT, peer B using EIP on Cloud

[mattkasun]

what is EIP?

what is EIP? Sorry, it may not be a piece of helpful information, EIP means elastic IP which binds the virtual router forward to Peer B
