Hello, first of all thanks for this amazing library!
I am configuring a P2P application where Peers communicate on different networks through UDP Punch Hole. While testing locally everything is working as expected.

Then I moved the Punch Hole server on a linux server with a public IP with port 15000 (which was opened). I can succesfully connect two clients using my ISP network, but unfortunately I can't connect two clients using my LTE network. I think that's caused due to Symmetric NAT that my provider is doing.

If I ping my linux server using my LTE network I go through these local IPS:

  1    <1 ms    <1 ms    <1 ms  192.168.2.1 //this is my router (firewall disabled)
  2     *        *        *     Time out. //this is probably the cell tower?
  3    85 ms    28 ms    23 ms  10.128.74.29
  4    34 ms    21 ms    23 ms  10.128.74.14
  5    22 ms    22 ms    21 ms  10.128.74.236
  6    34 ms    25 ms    24 ms  10.128.74.1
  7    31 ms    25 ms    23 ms  10.176.16.118
  8    39 ms    22 ms    23 ms  83.xxx.xx.xxx //this is the first public IP

While trying to establish a UDP connection, Phase 2 fails. In the Punch server logs I can see my LTE public IP and ports that was assigned to each client on Phase 1.

Can you help me with this? I know there is a way to do it, but unfortunately I am struggling in finding that.

Thanks!

Hello,
I'm trying to run the example of udp hole punching, when I try to start the UDPHoleClient I get the exception:

Could not resolve constructor for class com.codebrig.beam.system.messages.HandshakeMessage
