Usually the places you cannot get IPIP to work are the same places you
won't get GRE (used by DMVPN/OpenNHRP) to work as well. So that brings
us back to square 1.
Very basic NAT boxes handle TCP and UDP but rarely more. (Of course
there are boxes that do more, I know, but those boxes don't have the
issues we are looking to work around :-) ).
Some networks are firewalled and allow access to a few selected ports
only (e.g. 53, 80, 443), so we should be looking for a least 1 tunnel
protocol that can run over TCP or UDP (or even both) using a
configurable port.
