See today's article on Slashdot about WiFi and PPTP - there's a guy
commenting that he tried to setup an IPSec VPN (was it OpenSWAN? i don't
remember) and he couldn't descend below 150ms latency - definitely not
enough to play some network games.
With OpenVPN he got 50ms which is more than enough for pretty much all


Heh, I happen to be the friend he is referring to.  Small world, eh?

He's right, however: We did try freeswan. I originally set it up, and while setup wasn't *that* bad, the routing was a nightmare, like he said. Perhaps now I could have done it with some tweaks to the firewall rules, but that's not the point: We shouldn't have to.

We tried some bandwidth/latency testing ( *cough* Serious sam *cough* ) across the freeswan link, and it wasn't playable. Tried it across the openvpn link, no issues.

As an interesting side note: I will soon be implementing a voip solution for the offices I work for using openvpn and asterisk. I have absolutely no stress regarding link stability or latency consistancy ( only in my ability to work with asterisk...but that's a different mailing list altogether ;) ).
