Just thrown out the old Vigor 2830 router as the firewall/port-forwarding functionality seemed to be fundamentally broken.
Now I've got an RV110W and it's looking encouraging, but...
I want to set up a firewall rule to give my VPN user full access to our LAN.
I can create an access rule in the firewall section, there's something very odd indeed about the "Destination IP" select control. It says "Single Address" and I can't change it.
BUT, if I cut and paste that screen here, look what it shows! Extraordinary!!!
