Well, now the problem is that I have no idea what to add as MTU values
if I need to... Sven's "documented" problem and solution was to use
--tun-mtu, if that is the max sized packet that can go through
unfragmented it looks like the only option one should specify. And
--fragment seems to be needed always in addition to any of the MTUs?
Unless it's the default behavior?
