T-Mobile Home Internet doesn't support port Forwarding, any workaround?

[GEPP3N03]

Hi there,

I recently got my Dreamcast online again and while setting up the connection, I noticed that my ISP (T-Mobile 5G Home Internet) doesn't support port Forwarding or DMZ configuration. I read that It has something to do with the fact that the router uses ipv6 rather than ipv4 settings, so I doubt I would be able to change that. Is there some kind of workaround so I can play every Dreamcast game?

could use a vpn...i use purevpn as i have starlink which is cgnat not suppoting dmz/pf....purevpn has options to forward ports...if your router supports vpn you can configure there...also there is a way to install the vpn on your dreampi itself
