I also set up a TheDude server in my network as a vm. Added snmp community and all filled up with "discovery" option.
I tried to set up "loopback", router have to ask himself for snmp, but maybie i don't do it right. And someone know the problem for setting The Dude on gateway router.
SNMP settings via hap ac3:
The Dude on hap ac3, - snmp not working, tried all options.... The Dude - the same network, vm - worked all with "discovery" option: I think its a firewall? So i made this funky rule, but it shows 0 packets
