Good writeup, but why does this piece recommend running the VPN over TCP? Tunneling TCP over TCP, which will be the end result, is known to provide terrible performance in the presence of even minor packet loss.
- bensedat 13y agoGood point! I made the change when using the VPN at DefCon but haven't updated the post. I'll do that now.
- Scramblejams 13y agoCool. I was looking around a few weeks ago for a good howto on setting up an OpenVPN server, but didn't find anything straightforward enough for the time constraints I was under. Thanks for writing this up, it'll come in handy for me.
- Wilya 13y agoI've seen many networks blocking udp entirely. An openvpn on a HTTP tcp port (article says 80, I would say 443 is better) is much less likely to be blocked (openvpn also knows how to go through an HTTP proxy).
- agwa 13y agoRun two instances of OpenVPN - one TCP, one UDP. Always try the UDP one first. I've done performance comparisons and the difference is striking.
