Dear @_plip ,

In ER7206, I set "Get Trusted Host" to the public IP of the external snmp agent and enabled snmp, but I cannot connect via wan.

If you set "Get Trusted Host" to the LAN IP, you can connect from the LAN machine.

I remember that it was possible in ER6020 and ER6120.

++ Even if "Get Trusted Host" is set to 0.0.0.0, connection via Wan is not possible.

I'm afraid that it doesn't support yet at present.
This has already been forwarded to the TP-Link team for evaluation.
FYI, the function will be added back in the subsequent firmware updates. Cheers!

Best Regards!
