I am looking to buy a VPN subscription, and im interested in getting one that allows port forwarding. Found a few that still allows this, including pure VPN and air VPN which seem to offer good value for money, at least on the the long term plans. Any feedback on these two?

I used to have nordvpn, and used it for 3 years, and once that subscription ran out, have been using mullvad so far. Performance wise mullvad hasnt disappointed me or anything, but now im looking to find one that allows port forwarding.

I also have a doubt regarding the whole port forwarding thing, does the VPN having this feature enable to do it even if my ISP doesnt allow port forwarding? From the videos and articles I read, VPN port forwarding is just something you do inside their native apps and such, so if the ISP hasnt enabled port forwarding for me (which I know it hasnt, because tried to get jellyfin working the other day, and couldnt get the ports to open even after setting everything up in my router), will I still be able to do it? I tried searching around with this query, but didnt really find anything.
