It is pretty easy to turn off any roles you don't want on Streisand. If you know for sure you will be using IPSEC I agree with you, use the ToB setup.

Specifically, compare their IKE setups:

https://github.com/trailofbits/algo/blob/master/roles/vpn/te...

Algo's is much more conservative. Streisand lets 3des and SHA1 into the mix. If you allow it, users will end up using it.

Otherwise, I think you are spot on and I prefer Algo (having used both for various things and just playing around).

For anyone about to try out algo – I assume it's great if you are using AWS or DigitalOcean, but if you're self hosting, or have an unsupported VPS, I've had nothing but trouble getting it up and running. I am most certainly to blame, but just a heads up.

Not to toot my own horn, but here's a blog post I just wrote on some issues I ran into setting up Algo on a pre-existing Vultr server. It might help.

Excellent I'm embarrassed that I didn't ask if anyone had done this and wrote up their results.

From what I was experiencing, I bet it was either the root privileges, or the SSH connection errors. Thanks a ton.
