You said before that your firewall is blocking ping from your host, so it sounds like it *isn't* allowing all services. If you can get to the point where you can ping your firewall, you'll have a better change of being sure that you can open SNMP.
When you say "host to prometheus" I don't understand what you're saying. I think you were talking about two things: - the host where you are running prometheus and snmpwalk - the target device that prometheus/snmpwalk is trying to communicate with via SNMP (i.e. the Fortigate). The SNMP UDP query originates at the prometheus host, and arrives at the target device with destination port 161. The response UDP packet will have source port 161, but any half-decent stateful firewall will allow the response automatically. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
