TLS Errors

[NoelS]

I'm getting these errors in my Router Log (AC68U running latest Merlin). Anything to worry about or benign? Any adjustment to try?

TLS Error: unknown opcode received from [AF_INET]207.189.2.3:443 op=20
TLS Error: Unroutable control packet received from [AF_INET]207.189.29.3:443 (si=3 op=P_ACK_V1)
TLS Error: cannot locate HMAC in incoming packet from [AF_INET]207.189.29.3:443
TLS Error: local/remote TLS keys are out of sync: [AF_INET]207.189.29.3:443 [2]

TIA

Looks like standard port scanning. Expect to see a lot of that as you're using a common port (443).

Are you in fact running some service on port 443 of the WAN?

@eibgrad Nothing that I know of, other than the VPN
@ColinTaylor Ok, so it sounds like "nothing to worry about"?

Well you can only have one service running on one port, so that will be the VPN.

It's more of an annoyance really. Once the bots have seen a response on that port they keep coming back. Then over time more and more bots discover it. Just change to a non-standard port and the messages will disappear.
