IKEv2 VPN Blocked by ISPs

Hi all,

 

Recently I've noticed that IKEv2 VPN connections from Europe to FortiGate boxes in the U.S. no longer work.  In the past, one could use SSL VPN to get around this issue, but with all the problems using SSL VPN and it being phased out, what are folks using as an alternative?  Thanks

Didn't even think to use TCP.  Thanks for this!
