This is merely my observation. I don't understand the code. I feel that DCO should be compatible with Tap and Tun. Could this be due to some directives in the OVPN configuration file being incompatible with DCO? I learned about the dual-side acceleration for both servers and clients from the update notes of the ovpn-dco-win 2.x series. The 2.x series explicitly added a DCO server mode, while the 1.x series defaulted to client mode. Since two modes have been introduced, dual-side acceleration must have been implemented. The OpenVPN 2.7 series on Windows uses the ovpn-dco-win 2.x series driver, while the previous 2.6 series used the 1.x series driver. Comparing 1.0.0...2.4.0 · OpenVPN/ovpn-dco-win · GitHub

I think the DCO driver support in the OpenVPN 2.6 series is incomplete. The 2.6 series DCO server can serve non-DCO clients, but non-DCO servers cannot serve DCO clients. This is the result of my multiple attempts, after all, I am not a professional.

I believe AirVPN is awaiting the official release of the OpenVPN 2.7 series. The OpenVPN 2.7 series DCO adds dual-side acceleration for both the server and client, while the 2.6 series DCO only supports single-side acceleration for either the server or client. Furthermore, OpenVPN removed support for Wintun in the 2.7 series; future OpenVPN 2.7 series servers will only use the DCO driver. Let's wait patiently for a few more months.

I have many servers on my eddie that I can't test for latency, but I can connect to these servers using the OpenVPN protocol. What could be the problem?

Good job！

Thank you very much. Port forwarding has resumed normal operation again. It was an issue with the Windows 11 firewall. Although the firewall had previously been turned off, at some point it was automatically re-enabled—probably due to a Windows 11 policy. Once I disabled it again, everything worked fine. Thank you. I really appreciate your help.

eMule. I’ve already made sure that the eMule listening port matches the VPN’s forwarded port. Yet I still get a Low ID, whereas before I used to get a High ID. That shouldn’t happen—ideally, once the VPN tunnel is successfully established and the server forwards the port, the client should be able to communicate over that port through a properly open public network. The ISP can’t possibly intercept a port’s communication through the VPN tunnel, right?

Of course, none of my applications can connect through the forwarded port, and changing the port doesn’t solve the problem either.

There’s nothing listening on the port? I’m using Windows 11, the network firewall is turned off. I’m currently using Eddie version 2.24.6. Is port listening managed by Eddie? Is it an issue with my computer system? I switched to using Eddie on Android and still got connection refused. What should I do?

Is it my ISP blocking it? It used to work fine before, but it recently stopped working.

Hello, I can connect to the server, but port forwarding is not working. A port test shows "connection refused." I need help.

Thank you for your guidance.

I'm using China Broadcasting Network, and ever since I started using AirVPN, I've mainly used it for P2P sharing. After all, I first came across AirVPN through an ad on an eMule website, so I've always wanted to improve speed and connection duration. Unfortunately, due to advanced traffic shaping technologies, my connection has become slower and slower, eventually getting reset. At first, I had speeds of over 150 Mbps, but they gradually dropped to 8 Mbps, and after about 10 hours, the connection finally disconnected. I think my network environment poses a significant challenge for both VPNs and P2P networks. In the future, I may no longer use AirVPN for P2P sharing, and instead just use it for browsing. The basic circumvention service that AirVPN provides still works quite well for that purpose.

Your explanation was very clear, thank you. Although I'm not a professional programmer, I can understand it.

你的解释很清楚，谢谢。虽然我不是专业的程序员，但我能理解。
