In what manner do you want to connect? Client to server? Server to server? Client to client? Who is on what end of the connection?

 

Do you have access to both routers on the Double NAT network? You may be able to just eliminate the Double NAT.

If the client will sit behind the Double NAT this may work fine if the server can be port forwarded on the other ISP network.

 

Is it a File server? Game server? Web server? A VPN can get it done but if you can provide your own encryption SSH/SFTP, HTTPS, etc then you could directly use those protocols.

 

What OS is the server running?

the server is set behind double Nat...

and I need to connect to the server but the port forwarding don't work...

It's possible to make server vpn on the nat isp and the server connect to vpn server that on the double Nat isp? because both of the vpn server is on the local network...

This should work. Setup a Pritunl server on the network you can port forward on. Enable inter-client communication and have both servers join the VPN. Then both servers will be able to communicate with one another securely despite one server being behind a Double NAT.

 

I have a Pritunl tutorial that could get you started:

Nope. The VPN server has to be Port Forwarded so it needs to sit behind a single NAT. This is your "free" (or near free) option. Outside of this you could setup Pritunl on the likes of AWS, Google Cloud, Microsoft Azure, Oracle Cloud, etc then have the servers connect to that remote VPN but depending on how you would plan to use this that would come with costs.
