I have had an SNMP sensor working on a device for the last 18 months. I have now moved that device behind a firewall and have forwarded port 11161 on the firewall WAN to port 161 on the private IP and have configured the PRTG properties to use port 11161 for the SNMP traffic. (I want to use port 161 to monitor the firewall)
I get no response when I try to add a SNMP traffic monitor.
Have I missed something here?
Appreciate any thoughts.
