ANSWERED Help with port forwarding to VMBox Ubuntu from Windows.

[nleco 0]

I've been reading a few posts and I believe I had it set up at some point. It is no longer working.

Here is my setup.

• Host is Windows 11 Pro and have my Firewall disabled.
• I am running VirtualBox 7.0.12, with a Ubuntu 22.04.3 LTS, with the VM Network Setting set up as "Bridged Adapter".
• I am running AirVPN Eddie 2.21.8 in ubuntu along with qBittorent v4.5.5
• I have a port reserved under my "Your forwarded ports" section on airvpn.org/ports account.
• I have the same port set up in the qBittorrent Prefferences -> Connection -> "Port used for incoming connections", "Peer connection protocol" as TCP, and "Use UPnP/NAT-PMP port fwd" disabled.
• I do NOT have any port fowarding set up on my router.

I am confused about whether I need to foward a port in my router. The instructions here confuse me: https://airvpn.org/faq/p2p

Towards the bottom, it reads:
"IMPORTANT: do NOT forward on your router the same ports you use on your Bittorrent or eMule client (or any other listening service) while connected to the VPN."

qBittorent has a little "flame" icon in the bottom, stating "No direct connections".  The "Test open" button on the airvpn.org/ports shows that the connection is refused (111).

Hello!

You get a connection refused error (111) when the port is tested, meaning that the packets have reached your system and have been actively rejected by your system (and not silently dropped).

Please upgrade to qBittorrent 5 first. If the problem persists after the upgrade, please make sure that no packet filtering tool on your system blocks packets for qBittorrent. Also make sure that qBittorrent bind settings are correct: it must bind either to all network interfaces or the proper tun interface, and to "All IP addresses". Also, qBittorrent must start after the VPN connection has been already established.

Kind regards

Shouldn't I be able to test open ports via the airvpn site by clicking "test open"? That is where I am seeing the 111 code.

Hello!

Correct. 111 is the error code for "connection refused". Packets have reached your system and have been actively rejected by your system (and not silently dropped). Technically this occurs via a TCP RST, so the other end (in this case the port tester machine) can see the active reset. The "active rejection" can occur via a firewall configured to reject packets (instead of silently dropping them) or by the system when configured to reset an attempted connection to a non-existing port. Therefore, you need to check your system firewall rules, and the qBittorrent configuration (according to our previous message).

Kind regards
