MX Port forward snmp request

[StevePayne]

looking to remotely SNMP poll the AP  behind the MX,

have added a port forward, but the ap does not seem to respond

is this possible?

done a packet capture and see the traffic coming in

[KarstenI]

It should work as it is "normal" UDP traffic. Is the managed device (the AP) configured to respond to the public IP of the request?

BTW: What about using a VPN to manage the internal devices?
