ANSWERED I'm facing difficulties in enabling port forwarding for P2P networks.

[palomeque 0]

I've tried multiple times to set up port forwarding for P2P, but I'm still unsuccessful.
I'm trying to find the 4 ports I need available for port forwarding.
I assign them to the necessary local ports:
TCP 4661
UDP 4664 (TCP+3)
UDP 4665
I always, ALWAYS get a LOW-ID.
And when I check the availability of the previously reserved TCP ports, they always show as locked (red).
I've tried this with many different servers, but I always get the same result.
Thank you very much.

Hello!

Please do not "re-map" the ports, it's a critical error. Then, please follow this guide:
https://airvpn.org/faq/p2p/

Please note that the system may not update re-mapping in real time, it may take some minutes. To quickly apply the change, once you have deleted the "local" fields in your port panel and you have fixed your p2p program configuration, please disconnect and re-connect.

EDIT: Important, please make sure that you start your p2p program only after the VPN connection has been successfully established. If you disconnect the system from the VPN, then shut down the p2p program, re-connect the system to the VPN, and then re-start the p2p program. Furthermore, if you run Windows, you must check the firewall rules while the system is in the VPN, as the Windows Firewall can change rule set (especially for incoming packets) according to the network type the system is connected to.

Kind regards

Well. Even after 48 hours, I still can't get it to work or understand it.

    I search for 3 sequential free ports because I need TCP and UDP (TCP+3) available. "There are 3 sequential free ports between 21811 and 21813 inclusive."
    It indicates ports 21811 to 21814, but I assign 21811 (TCP ONLY), 21812 (UDP ONLY), and 21813 (UDP ONLY), not reassigning local ports as indicated.
    I assign the proposed ports to my client-side zone: TCP 21811 + UDP 21813.
    I configure my p2p client with these ports. No matter how long I wait (214 or 48 hours), or which server I choose, THE PROPOSED AND SELECTED TCP PORT IS ALWAYS REJECTED, and I always get a LOW-ID.

My primary issue with AirVPN is the consistent inability to locate a free TCP port for port forwarding. Despite numerous attempts, I've always encountered this problem.

Kind Regards.

@palomeque

Hello!

A couple of additional critical errors that are visible on your last screenshot and how to fix them:

• wrong value in the field Bind local address to IP. You specified some server public IP address instead of the proper VPN IP address. Fix this error by leaving the field empty anyway, as the VPN IP address may change between connections
• UDP port for server requests (21814) is not remotely forwarded. If you really need that this port is forwarded and it must have "TCP port +3" number, then you need 4 contiguous forwarded ports, not 3 (1 + 3 = 4)

Kind regards

Thanks, true.
Bind value empty now (solved)
but....
then never unable to find 4 contiguous forwarded ports
nor manual selected

Hello!

Yes, currently it's not possible to find 4 contiguous free ports. We're close to implementing a new remote port forwarding system that will solve the port exhaustion problem once and for all.

In the meantime please check the graph by clicking the View graph button in your port panel and pick a port n for which port n+3 is free, there's plenty.

Kind regards
