There is not a way to add an OID to a device from the DUDE client if the client machine is outside the firewall (can’t access the device directly). There is an option for performing an SNMPwalk from the local computer or the server. Can an option be added to add an OID from the Server standpoint in this scenario?
We changed the behavior of OID picker to perform SNMP walk from server. This will be in next version.
