I cannot get the SNMP sensor added despite SNMP Tester confirming there are standard interfaces present.
The PRTG host (10.1.0.0) is behind a firewall and we are monitoring a remote firewall (10.2.0.0). SNMP tester can communicate with the remote firewalls' outside interface.
When adding the SNMP sensor the remote firewall is showing a UDP drop from the probe on 10.2.0.0 to the outside interface of the remote firewall
Can you please advise what we have got wrong?
