NAT using Foo-over-UDP #109

Closed ymmt2005 closed 3 years ago

ymmt2005 commented 3 years ago

This PR adds a set of structs that implement NAT client and server as a whole.

NAT client and server communicate over Foo-over-UDP tunnel. The implementation supports both IPv4 and IPv6.

Package: pkg/founat Structs:

FoUTunnel: receive FoU UDP packets and create tunnel devices
NATClient: registers egress networks with the routing table
Egress: configure NAT rules
