vnet-udpproxy

This example demonstrates how VNet can be used to communicate with non-VNet addresses using UDPProxy.

In this example we listen map the VNet Address 10.0.0.11 to a real address of our choice. We then send to our real address from three different VNet addresses.

If you pass -address 192.168.1.3:8000 the traffic will be the following

   vnet(10.0.0.11:5787) => proxy => 192.168.1.3:8000
   vnet(10.0.0.11:5788) => proxy => 192.168.1.3:8000
   vnet(10.0.0.11:5789) => proxy => 192.168.1.3:8000

Running

go run main.go -address 192.168.1.3:8000

You should see the following in tcpdump

sean@SeanLaptop:~/go/src/github.com/pion/transport/examples$ sudo tcpdump -i any udp and port 8000
tcpdump: data link type LINUX_SLL2
