CGNAT/IpV4/IpV6/Port Forwarding for gaming etc.

[McGraw]

I'm about to get BRSK which needs £5/mth extra for staticip.

I only need port forwarding for SPTarkov and DCS world

The people I host for are on BT ADSL

Is there some way we can both just use IPv6 or something to stop me needing a staticip/VPN?

Thanks
