we have a EMC Isilon which responses to SNMP requests with an different IP than the IP we requested to.
For example we request the OID 22.214.171.124.4.1.12126.96.36.199.0 to destination IP 192.168.1.1 and the SNMP response is from source IP 192.168.1.2.
SNMP Tester says no response but the snmp custom sensor in PRTG itself is working.
So is that a bug in SNMP Tester? Or a missing feature?
