I am struggling with BI5, I have a BT Openreach modem with a LinkSys Velop as my NAT/DHCP/WiFi router (I needed Velop as a mesh system in a very old cottage with thick walls but connecting it do my BT router resulted in a double NAT issue - hence the modem). When I run the Remote Access Wizard I get a wrong Server response to HTTP 'Listening on Port' screen. If I go to CanYouSeeMe.org it can see my IP:81 port.

Anyone have any idea what id causing this?

Thanks
