I am trying to get SNMP info from the router to H2 but snmpwalk errors with no response from router. I can get info from H1 and neither interface on router is preventing SNMP traffic from coming or going.
Is there something that needs to be configured to allow SNMP traffic (orginating from INSIDE) to reply? (Also note that there is no Inspect Maps blocking and SNMP versions).
So you mentioned that the SNMP traffic will be originated from the inside (from H2)? If there's NAT and ACL permission, then it should work. You can do a Packet Tracer test from ASDM or from CLI to see if the traffic is passing through fine.
