[arm-allstar] Supermon, outside hotspot access of mobile node

[Doug Crompton]

We have many mobile hotspots running on the Philadelphia hub as people
travel and they work well in most cases. Knowing the IP address is NOT the
issue. When you register with Allstar your public IP address is in the
database and passed to all other nodes that are registered. If a mobile
node registers its IP address is in the Allstar database. However that does
not mean you can connect to that IP address as the hotspot is nat'ed behind
it.

Mobile nodes work fine connecting TO a fixed node that has port forwarding
but most mobile hotspots do no offer a port forwarding option for incoming
connections. There are also other "nat'ing" issues within the network that
might preclude being able to connect TO a hotspots IP address and establish
a connection.

I am not sure what all the fuss is about this since a hotspot operated node
by definition is not always online or often online for a short period of
time. Therefore once the portable node becomes established on the network
(10 minutes or so) just connect out from the portable hotspot node to
another fixed node. There is really no reason to have inbound connections.
Establish a node you connect to when you are portable and if someone wants
to find you they can connect there.

Also not all providers are equal and not all work in the same way. AT&T for
instance has a connection problem that we have a fix for.
