Re: No Port Forwarding option in Security Menu for Virgin Media Router
Ireland, by any chance?
VM in Ireland are using CGNAT, which means you're getting put behind a NAT that's running at VM's end. There's no point setting up a port forward on your router because inbound connections won't ever reach your router unless you also set another port forward up on the router inside VM's network, which you can't do.
(Not sure why pings aren't getting though; Windows has its own firewall that -- incorrectly -- blocks pings out of the box, so it might be because of that.)
