i was able to ping the UML from another machine on the network, and was able
to ssh into it. i can ssh and ping the uml from my machine 9.174.101.45, but
cannot ping this address from within the UML. this leads me to think it is a
routing problem on the host level...

this is correct - both uml-conn0 and eth0 on the host are set to 0.0.0.0 and
promisc. eth0 in the uml has the proper IP.

i want each UML to have it's own IP and access to and from the outside
world, as if they were a normal host. what's the other way of achieving
this?
