This short guide explains how to connect two IRI nodes behind firewall/NAT using UDPeer. You will need a host who is willing to pair with you. There is no need to open any firewall ports or NAT. It just works. We have also tested it across Windows and Linux hosts.

UDPeer is a bidirectional UDP proxy using webrtc for communication. https://github.com/akashgoswami/udpeer
