I’m using a PepWaveMAX BR1 Mini. Simm card is connecting to Verizon. I have a device that is connected on the LAN side and it needs to use a specific outbound UDP port (high numbered 53118) for connection to the remote server. However when the packet arrives at the remote server…it’s being translated to a low port number (5907 for example). I’ve tried adjusting outbound Firewall and NAT rules to try and make the modem not alter the port from the specific LAN IP but have’nt been able to make it work so far. Other than the adjustments to the Firewall and NAT rules, the modem is running in it’s default config. Firmware was upgraded to the latest about two weeks ago. Does anyone have an idea about what to try next…???
