Need to configure XB7 gateway to allow L2TP/IPsec VPN.

If my memory serves me right, the VPN that I occasionally use worked before I upgraded to the XB7 Gateway.  I have tried all of the suggwated solutions short of port forwarding and nothing worked.  I even disable the firewall and it still won't work.  The VPN connects my Windows 11 computer to a CISCO firewall in another state.  Could this be a XB7 mproblem and I need to swap it out?
