Client listening to TCP, Server listening to UDP (both ubuntu server 16.04 64bit)

Hi,

I am doing my master thesis on NAT traversal and wanted to try your tool pwnat.

I wanted to test two linphone clients.
On one of the clients the server side is running (192.168.0.121):
sudo ./pwnat -s -v 3333 &

The other one has the client side running (192.168.188.70):
sudo ./pwnat -v -c 5060 192.168.0.121 3333 192.168.0.121 5060 &

It is not working so far. The client displays, that it is listening to a tcp connection,
while the server side is listening to a udp connection.

Is there something wrong with my program calls?

EDIT: The first address of the client command has to match the WAN IP of the server:
sudo ./pwnat -v -c 5060 192.168.188.2 3333 192.168.0.121 5060 &

BR,
Chris
