Blocking incoming connection on RT-AC68U stock firmware

[thasan10]

Hello all,

I have an RT-AC68U where I have setup an OpenVPN server. The problem is now, I have a set of IPs from outside trying to connect (obviously not me). They do not manage to connect but keep trying. Is it possible to setup a rule to block a subnet from connecting? I tried using Port Forwarding to forward the traffic to a non-existing internal IP but I didn't success obviously.
Help appreciated.

You may want to determine who the IP addresses belong to. Use this website for that: https://tools.keycdn.com/geo

I know who it is. I still wanna block it.

I doubt you can block it using just the options available in the stock firmware's web interface.

The same question was asked here and as you can see even if you were using Merlin's firmware you'd have to create two user scripts.

A simple but effective approach is to use a non-standard port for the VPN server.

Thanks for the input. I have considered changing the port for a different reason. This will give me one more reason to do so.
