I suspect you may be missing (in the export RUMP_SERVER=$sock_gw block)
something equivalent to
	rump.sysctl -w net.inet.ip.forwarding=1
(add -q if you like.)  (I don't know if there is a rump.sysctl, but there
must be a mechanism to allow that to be done...)

And while the little diagram you drew might be a logical descr of what
you're configuring, I think a more accurate one would be:

#    ===================================================================
#           |                        |                         |
#           |           +---------------------------+          |
#  int      +  +     ext
#                       |            gw             |
#                       +---------------------------+

gw would need to be configured with shmif0 & shmif1 to accurately
model the original diagram.   Not that this should really matter
to the test you tried.
