I've developed a Python application which rotates VPN gateways from one or more providers. This will change your outbound IP address, and optionally VPN provider(s), on a random basis within a given time period (eg, every 2-4 hours). This uses Docker, the Gluetun VPN client, virtual machines, and optionally HAProxy, MQTT, InfluxDB and Unbound DNS.

I'd really appreciate feedback from members of this subreddit, whether that's in regards to the general concept, the example architecture I've included in the repo (below), the code itself, or whatever else you might have!

Randomizer supports all providers supported by the Gluetun VPN client including custom providers. The randomizer project has been biased towards Wireguard and Linux, with OpenVPN and other OSes in near-term consideration. It's my intention to keep the project as flexible as possible allowing ease in adopting personal modifications.

That's cool AF. Do you have any moments of connectivity in between VPN switches?

[–] ingestbot@alien.top 1 points 11 months ago

A most excellent question and an issue just recently addressed.

Gluetun includes a control server which allows state changes to the VPN connection. Early on I would send a stopped and let the healthcheck take care of the recovery. At some point I found that 6 second lapse to cause a bit of trouble so I played with sending a stopped and immediate running. The result is a near instantaneous recovery (and random reallocation) of the tunnel.

Here's are a couple of examples:

You've raised a great point here and it's something I may look into further (as in soon). It wouldn't be to difficult to measure the entire sequence in milliseconds and offer that up as a metric.

I just use VPNgate with its 100-300 vpn's to rotate if needed. But in general when using python , 99% of the time you can do just fine with a rotating proxy setup (socks5) , just bit of scraping online and et voila.

[–] ajicles@alien.top 1 points 11 months ago (2 children)

Could probably do this easier with PFsense and setup all of the VPN clients on the firewall and write a script to stop and start each vpn service. I use PFsense for torrents to allow load balancing and to increase throughput. I have three openvpn clients setup into a gateway group and tunnel the traffic out.

[–] nocsupport@alien.top 1 points 11 months ago

pfSense can just keep all the VPN sessions up. You make gateway groups that can be triggered by timers. "At 12:37 these clients should use this gw group which favors this VPN "

[–] ingestbot@alien.top 1 points 11 months ago

Supporting appliance based tunnels would probably be a clear path for this project. Challenges may involve key handling and gateway/provider management. If there were a dependable, native API this could make it all the easier.

My little project so far has been biased towards (a surplus of) redundant commodity hardware. The environment where this evolved includes a very early MIPS32 based router so tunneling/proxying/resolving were not an option there.

I'm most definitely inspired here to see about supporting this kind of configuration! pfsense/opnsense have been on my list for years.

I don't get the hate, this is very cool, thanks for sharing!

[–] ingestbot@alien.top 1 points 11 months ago

Thank you very much. In fact, the more challenging comments and questions inspire new ideas and shine light on knowledge gaps. Some of the funner comments help sharpen my dulling wit.

[–] bzImage@alien.top 1 points 11 months ago

Make it so you can chain vpns.. 1 random vpn over another random vpn

[–] Brilliant_Sound_5565@alien.top 1 points 11 months ago

Nice project, couldn't see me using it myself as I'm not sure why I'd want my VPN to randomly change every 24hrs say? You say the router is a spof, but that's still going to be the case here isn't it?

[–] pyotrdevries@alien.top 1 points 11 months ago (1 children)

Since I'm not seeing anyone else say it; I think it's a cool concept and the first time I've seen someone make this. I can imagine this being added to one of those ultra privacy focused bootable Linux distro's. Nice work!

[–] ingestbot@alien.top 1 points 11 months ago

Thanks tons kind sir. A warm muffin to you!

[–] Diavolo_Rosso@alien.top 1 points 11 months ago

Cool idea but a lot of work for nothing. Every provider offer multiple gateway around the world with a couple of click

[–] Intransigient@alien.top 1 points 11 months ago

Have you thought to encrypt and segment each data frame then send them out in a random order over those multiple gateways, for decryption and reassembly at their destination? Two endpoints set up in this manner could provide significant security, since not only would each frame be encrypted, but the reassembly order would not be determinable via en-route packet sniffing.
