I have tried to setup a VPN client on this router but so far have failed. I am using Surfshark and have tried both Wireguard and OpenVPN protocols. I have also tried to connect to 2 different servers, Bend and Seattle. In each case the connection is shown as having been made, but when checked both IP leak and DNS leak tests fail!!! Is this a known issue with this router? Is there a fix available? As you can see, I am using the most recent firmware update.
