Server in docker, android APP send udp to container ip


My server set on a docker container has IP and the host’s public IP is I configured NAT for the two IPs and single port 20000 in ~/.sip-communicator/ I found that Android app sends UDP packages to and both. is not reachable in WAN. How to explain this behavior?


Where are you seeing this? A wireshark trace? The bridge will have advertised that IP address so the Android app will prove it.


In android emulator and tcpdump in PC.


Is docker running on the PC where the emulator is running?


Docker is running on a PC in WAN and emulator is running in my PC. tcpdump in my PC.


Can you see the SDPs? If the Jvb is advertising the local address then this is expected.
