[strongSwan] Strongswan gives Strict-NAT: How to change that?

Hello all,

due to internet censorship, we have to use VPN to access Online Gaming services with our Xbox One.

There are no issues with using Strongswan generally - it works perfectly on my desktop and mobile devices.

But when we are using a VPN connection with XboxOne, we always get Strict NAT which in turn restricts the possibilities for using Xbox.

Without VPN, we always have open Nat.

So I wonder are there some configuration options that might help?

I have installed Strongswan 5.5 on a Ubuntu VPS and set up a (ikev2) VPN connection on our Windows 10 laptop that we share with the Xbox One. You cannot connect directly to a VPN with Xbox, therefore this workaround via the laptop.

I hope somebody has some ideas on how to get open or moderate NAT.

Thanks a lot for your help!
