Hi, thanks again for the help and the quick reply. I tried using GRE support built into OVS but I think I am using it in the wrong way, as I do not have an OVS at the remote host; this is because I just want to connect multiple remote hosts to a single OVS running on a remote VM.
To give a bit more info, this is what im doing: I am using the gre built into OVS on the central machine running the only OVS in the system, but on the remote hosts I am using the iptunnel functionality built into linux to create the other end of the tunnel. Will this work? If it's not possible to do what I am trying to do I will just move all the VM's onto one machine that’s running OVS and use tap interfaces to connect them, but I would prefer to keep the VM's remote if possible.

GRE packets can encapsulate either Ethernet frames or raw IP directly. > Is there any other method you can think of to link them up as an alternative > to the methods I have tried? Would a L2TP tunnel work? You should use the GRE support built into OVS. If that doesn't work then something else is the problem. ----- No virus found in this message.
