can you please tell after 4 years plzzzz
not all are vpn providers. but they have port forwarding solutions.
https://web.tunnel.my.id/ and https://portmap.io/ provides vpn based port forwarding.
I checked them all out.
Added to that https://ipjetable.net . This one is even better, you get a public IP allocated to you on your VPN interface.
lol here I am 4 years later too
i found that portmap.io is by far the best. just look up a tutorial.
