I'm having problems communicating with a remote server, with openvpn. I can link with ssh ok, but the link stalls when viewing any but the smallest texts. I tried reducing the tun0 MTU, though only from 1500 to 1400, but this seemed to have no effect. Before trying a larger reduction, I'd like to clarify two points. Firstly, is it necessary to re-boot the remote machine for the change in MTU to come into effect? Or is it sufficient to re-start the openvpn service? (I'm reluctant to re-boot the remote machine unless it is essential.) Secondly, must the MTU be changed at both ends? Any info on these two points gratefully received. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Second, what exactly are you doing/do you want to achieve? VPN makes sense if you go thru a triangle (client -> network a -> network b, where b allows access only from a) or if you want to secure certain kinds of remote connections, but encapsulating an SSH link with a VPN tunnel makes not much sense in my eyes.
