[TL-ER6020] SNMP port 161 open to Internet
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I have enabled SNMP but I noticed that the UDP port is open to the Inernet. Is it possible to enable SNMP only from LAN?

Does it really work the WAN side? I doubt...
As I know, Policy Routing rules will not work for the router itself, so it is useless to configure it in your case.
Have you tried to configure Firewall > Attack defence? Try to enable everything and check, what will happen. Also, try to configure Get/Set Trusted Hosts to be only for your LAN.

If you disable SNMP, port 161 will become closed?

Yes, once I disable SNMP the port 161 is closed.

I think this SNMP feature is only used for LAN and we cannot access through WAN port.
I listened that ER6020 may release the new firmware soon. Maybe you can have a try at that time.

I tried to set Get/Set Trusted Hosts to LAN IP but it didn't help. The UDP port is open on WAN interface once I enable SNMP

I got a ER6020 and did the test with the software of nmap, did not find the open port of 161. Maybe you can post your screenshot to show us the detail.
