ConnectPort SNMP is UDP port 162. Can't change

When enabling Network Management Protocol (SNMP), the UDP port appears to be dynamic, with 161 being default. I see deny’s in my firewall for UDP 162. The SNMP is working, but the default port 162 and I can’t change. I’d rather not modify the firewall rules if possible.

Enable Network Management Protocol (SNMP) - Enable the controls just below for the Simple Network Management Protocol. Port 161 UDP is the default and may be changed here if needed.

NOTE: UDP port 162 is used for receiving SNMP traps from devices.
