[ovs-discuss] tunnel between open vswitch on xenservers

[terryxing]

Thanks for your timely reply.

Right, we are using two public ip for two remote hosts talking to each
other. I am wondering if it is possible to let two host in private network
talk to each other through their corresponding gateway having public ip ?

In that way, we need to configure the potables on the GW and do NAT. Do you
know what port the gre tunnel is using to talking to remote hosts ? And it
is using UDP  right ?

Thanks,
