SNMP Firewall rules

[Megachip]

Dear OPNsense Community,

it seems that none of the guides fror SNMP take the firewall into account...

Seems even on LAN interface, no snmp requests are allowed. Are there any preconfigured rules for SNMP?
It's ended up in Default deny / state violation rule, but I cant search for Id (windows will just reload)

Thanks a lot,
meg
