I'll do my best to explain this setup correctly
I have my iPerf server listening on port 5201
IP of the pc running the server is 10.xxx.xxx.131
PC is connected to a modem (default gateway 10.xxx.xxx.129)
Modem is connected to a router (WAN 10.xxx.xxx.134 and LAN default gateway of 192.168.1.1)
Behind the router are my client devices (192.168.1.xxx) running iPerf and trying to connect to the server.
I am trying to port forward but not able to find the correct solution.
Port Forwarding Options (on router):
External Port:
Internal Port:
Protocol: TCP+UDP
Loopback:
iPerf on Client device:
Server Address: 10.xxx.xxx.131
Server Port: 5201
