comment How do I improve OpenVPN reliability over a high latency link?
By default OpenVPN sets the MTU of the tun device to 1500 (which is the same as the MTU on the ethernet devices on our machines). I'm still not sure whether fragmentation of the VPN packets is a good thing or a bad thing. The answers in this thread seems to imply that it is bad, while the other references I found on the web implies that it is good.

Thank you for all the answers, but I've had to temporarily stop because the BGAN unit ran out of airtime. I'm hoping to cointinue later today. I should mention that we'd prefer staying with UDP, as using TCP would double the data sent over the network (and hence the cost, for which our client is already very sensitive)

This is interesting - It mentions that the TCP accelerator is available for Redhat, while the inmarsat people we spoke to said that it was only available for Windows and OS X (and this is indeed what the Inmarsat/BGAN website says)

Thanks. We're using UDP at the moment, and trying TCP never occured to me. (If I had more rep I would've upvoted you)
