AC68U closing firewall ports

[robp]

I'm hoping someone can help me, I'm new to Asus routers -just switched from draytek - and I'm trying to close some ports on the firewall. I've got a nas box on my network that I connect to internally via ssh on port 22 and I assumed that this port would be closed on the router firewall by default until explicitly opened but my nas is logging a lot of failed login attempts on port 22 so it must be open to the world.

How do I go about closing it on the router as there's no clear way to do this that I can see?

It's probably just something I'm missing but as I mentioned I'm used to the dark firewalls that are a lot more configurable and closed down by default.

Any advice is greatly appreciated!

Make sure on the Firewall tab, 'Enable Firewall' is set to 'Yes'.

If you are using Merlin fw, on the Administration/System tab, make sure 'Allow SSH access from WAN' is set to 'No'.

You probably have UPNP enabled on your NAS, which automatically forward that port. That port is not automatically forwarded (and this has nothing to do with open ports BTW, an open port would be terminated on your router itself, not on a LAN device).
