fwd: a tool for peer to peer port forwarding
Today I am releasing fwd, a tool for port forwarding between peers, through the firewalls and NATs separating the peers. Fwd achieves this without the need for firewall configuration. The only requirement is that each peer is running an instance of fwd.
To set up a forwarding session, fwd negotiates a peer to peer tunnel between the local and remote peers using a technique called Interactive Connectivity Establishment (ICE). Forwarded data is sent through this tunnel.
Fwd is cross platform and runs on Mac, Linux, and Windows. Read more and download fwd here.
