I think the basic problem is that something is masquerading you. If
that's not necessary, then turn it off. The natural state of affairs
is for the UML IP address to be visible to the outside world.

Jay:
It sounds like your host machine is already changing the source IP address of
packets going from the UML to the outside world, most likely through an
iptables masquerading rule, as Jeff pointed out.
How is the host machine connected to the internet? Does it go through a
router that does NAT or does it own a public IP address?
How did you arrange for the UML to get packets to the outside world? Does
the host forward the packets or did you bridge tap0 to eth0 on the host
directly?
It won't do you any good to get rid of the masquerading rule on the host if
you don't have another public IP address to assign to the UML.
