Port Forwarding Issues

Ive got a VPN server running on my home network which has been working well for some time.  I moved to a new location and after attempting to set up port forwarding on my Xfinity gateway via the Xfinity App, the port forwarding does not work.  I have advanced security disabled and have had no luck with the following ports.  UDP 1701, 500, and 4500.  It seems that they are blocked regardless of what I have done.  I have tried UPnp and manually configuring.
