I've made a Linux shell script for batch-conversion of WireGuard .conf files making them AmneziaWG (awg) compatible: https://github.com/zimbabwe303/awg_conf_patch When patching it shuffles the H1..4 parameters; to re-shuffle you can just re-run it over the same files again. It also can shorten .conf file names generated with the AirVPN config generator to facilitate their usage with the 3rd-party smartphone WireGuard clients such as WG Tunnel (which uses AmneziaWG instead of the vanilla WireGuard).

Hi all, I've always been trying to maximize my seeding speeds when using qBittorrent, and a lot of information I found online was not very helpful. My setup is qBittorrent 4.3.9 from hotio with Gluetun on TrueNAS Fangtooth. My best speeds have been obtained on the servers Taiyangshou and Vindemiatrix with WireGuard. I am in North America, but I don't think latency matters as much as I originally thought for P2P use cases. These two servers in the Netherlands have been very nice and I definitely recommend trying out different servers. In my use case, I have hundreds of larger torrents, maybe half are 50 GB+. I have found that since I am using hard drives, the random reads will quickly overwhelm them even with ARC and L2ARC, thus setting the "Global maximum number of upload slots" is very useful (this is the only one I have turned on in the "Connection" tab). This limits the total number of peers you can upload to globally, and the idea is that you limit the total amount of random reads this way. The magic number that works the best for me is 50, and I recommend trying around this range by increments of 5 might work nice. Additionally, I could keep increasing the "Global maximum number of upload slots" without much rise in iowait, but total throughput would decrease. Therefore, when optimizing this setting it is a balance between enough slots to saturate your bandwidth, but not too much where it spreads the bandwidth too thin and negatively impacts total throughput. I have also attached the advanced settings that I changed which seemed to make the greatest impact. Send buffer watermark: 6144 KiB Send buffer low watermark: 3072 KiB Send buffer watermark factor: 200 % Socket backlog size: 4096 I hope this is helpful! Best, Hypertext1071 Edit: For further tuning this might be helpful: https://github.com/felikcat/seedbox-tutorial. Edit 2: Using the settings from here: https://github.com/felikcat/seedbox-tutorial, including the sysctl configuration completely saturate my line speed. I was trying to search for qBittorrent in particular, and thus wasn't able to find results that were generally helpful, such as network tuning.

To give some numbers, with these settings along with MTU tuning (1440 in my case since no IPv6): I have been able to roughly 2.5x my speeds from 400 Mb/s average to 1000 Mb/s average which is essentially my line speed. Also, I have seen people ask about how to use Gluetun + qBittorrent in other posts, and this is where I learned how to do it: https://wiki.serversatho.me/. I hope these resources will help!

Hello I would like to give my personal recommendations to help with network censorship in Russia. I may not have time to write a authoritative, proper guide, but wanted to share this. Everything "clicked" once I read a comment how the DPI works to determine a new connection. Preface IP and subnet blocks came first. They completely blackhole all traffic to blocked IP addresses. The only thing you can try is IPv6 in place of IPv4. Some Air servers are blocked by IP. The Deep Packet Inspection (DPI) is a required installation for residential ISPs and (as of late) industrial networks like data centers. It works to dynamically block known protocol traffic, anything "forbidden" that's not yet in IP blocklists from above. This system was put in law many years ago. Nevertheless, the networks across the country are at various stages of rollout and their capabilities will differ. Real example: residential ISP did not block OpenVPN->Air, yet the mobile carrier did. Yet in 2024 the residential ISP upgraded their DPI system and started blocking OpenVPN too. Common methods of circumvention Mangle traffic locally to fool the DPI systems. It will allow you to connect to servers not blocked by IP (TLS SNI name detection). Proxy/VPN server: A prerequisite is an outside server, it must not have been blocked by IP. If it's a private server and OpenVPN or Wireguard work - you're lucky. However be prepared to still get blocked by DPI any day for using a VPN protocol. There are many proxy tools, especially developed to combat the Great Firewall of China. They don't run directly on Air, so this is something for self-hosting or other services to provide. We're talking about Air, so let's get that VPN working. Everything below requires you to find a reachable Air server (no direct IP blocks). The configuration server used by Eddie is IP blocked, so it won't work at all. I suggest you to generate all server configs in advance and see which are reachable from Russian networks. Airvpn.org seems to be reachable though. OpenVPN over SSH to Air It is possible to set this up on mobile, however the connection is reset after 10-30 seconds due to a lot of traffic being pushed. I used ConnectBot and it didn't restart the SSH connection properly, anyhow OpenVPN and ConnectBot had to be reconnected manually each time --> unusable. Since both apps are easily downloadable from app stores/F-Droid, this can be enough to generate and download configs from AirVPN's website in a dire situation. This connection type works like this: SSH connects to Air server, forwards a local port -> Air (internal_ip:internal_port) OpenVPN connects to local_ip:local_port and SSH sends the packets to Air's OpenVPN endpoint inside this tunnel Once the connection is established, it works like a regular OpenVPN on your system OpenVPN over stunnel to Air I haven't tried, desktop only? OpenVPN (TCP) over Tor to Air While connecting to Tor will be another adventure, do you really need a VPN if you get Tor working for browsing? If yes, I suppose it could work. I haven't tried. OpenVPN (TCP) to Air May start working after hours on Android, if the connection was established initially. Until then you'll see a lot of outgoing traffic but almost zero incoming traffic (NOT ZERO though!) It is unclear to me whether this is because Android keeps reconnecting after sleeping or sometimes it pushes so little traffic over the established connection that DPI forgets or clears the block for this connection only. OpenVPN (UDP) to Air Doesn't work. Wireguard to Air Doesn't work, it's always UDP and very easily detected. AmneziaWG client to connect to standard Wireguard Air servers This worked for me almost flawlessly. The trick of AmneziaWG is to send random trash packets before starting the connection sequence. This is what the new parameters are and some of them are compatible with standard Wireguard servers. The DPI only checks traffic within the initial traffic size window of the connection. If it doesn't find VPN connection signatures (and it doesn't due to random data) then it whitelists the connection. Wireguard then sends its connection packets and connects to Air. Full speed ahead, no throttling. The VPN connection works! What's the catch? The AmneziaWG packet configuration must be right. This worked for me across all networks I encountered: MTU: 1320 (safe value, higher MTU will give better bandwidth, if it works at all and doesn't begin to fragment packets) Junk Packet count (Jc): 31 Junk Packet minimum size (Jmin): 20 Junk Packet maximum size (Jmax): 40 Init packet junk size (S1): none (afaik only with AmneziaWG server; delete from config or try to set 0) Response packet junk size (S2): none (afaik only with AmneziaWG server; delete from config or try to set 0) Magic header settings changeable afaik only with AmneziaWG server: Init packet magic header (H1): 1 Response packet magic header (H2): 2 Underload packet magic header (H3): 3 Transport packet magic header (H4): 4 Example: [Interface] ... other default values, including MTU ... Jc=31 Jmin=20 Jmax=40 H1=1 H2=2 H3=3 H4=4 And how would you know what numbers to set? This single insight: This means flooding small random UDP packets at the beginning is the winning strategy. That's how I optimized someone's config from "sometimes it works, sometimes it doesn't" to "works 100% of the time, everywhere". You actually don't want to blast big packets and be blocked because of it. Smaller random packets are good for mobile traffic too. How would you setup AmneziaWG to connect to Air (Android)? Generate and download AirVPN Wireguard configs, for each individual server, try different entry IPs too. DO NOT USE THE DEFAULT (OFFICIAL) WIREGUARD PORT. We don't want long-term logging to highlight the working servers for the next round of IP blocks. Download AmneziaWG-Android VPN client (the Android edition is actually a fork of the official Wireguard app aka "AmneziaWG". Don't download their regular all-in-one client aka "AmneziaVPN"!): amnezia.org or https:// storage.googleapis .com/kldscp/amnezia.org or https://github.com/amnezia-vpn/amneziawg-android/releases Import Air's configs in the app Apply "Junk Packet" settings from above Try to connect Try different entry IPs and servers if the connection doesn't work. See if the server IP is completely blocked either with: ping "<entry IP>" nc -zv -w 10 "<entry IP>" "<port 80 or 2018 for OpenVPN TCP>" This is GNU netcat Keep in mind: on Android the safest way to avoid any traffic leaks is to go to system settings, Connection & sharing > VPN, or search for "VPN", click on (i) for advanced settings, Enable: "Stay Connected to VPN" & "Block All Connections not Using VPN". If you ever disconnect from VPN by using Android's system notification, you'll need to re-enable these settings. If you switch between VPN apps (like Eddie -> AmneziaWG), I suggest to make sure these settings are always enabled like this: Turn off Wi-Fi (or mobile data) For previous VPN app disable: "Stay Connected to VPN" & "Block All Connections not Using VPN" For next VPN app enable: "Stay Connected to VPN" & "Block All Connections not Using VPN" Turn on Wi-Fi / connect using next VPN app Android battery optimization: Finally, go to app's settings (or Settings-Battery then app list somewhere) and make sure the AmneziaWG app is "not optimized" for battery. This way it will not be interrupted in the background and potentially drop connection until the screen is awake. -- https://dontkillmyapp.com/ for guides and more info Thanks for reading.
