Research direction
This issue is a tracking issue for NAT traversal support. The discussion in linked issue #636 may contain initial ideas. Implementation would involve modifying Grin's network layer, specifically handshake and peer discovery modules. Research the current P2P architecture and possible Rust libraries for hole punching.
