You could try to use "IP Source Routing" to contact internal hosts on the
destination network. Some versions of ping allow you to set the source route
option in your pakets using the "-g" option, you would use the outside
router of the destination network as gateway and if that does not work, try
to add a dmz host as second gateway.
