Lets get this straight (apologies for the bad ASCI):

                                Internet router
      Some subnet (                Same subnet (
                 |                                        |
              m0n0wall                              Internal router
                 |                                        |
               172/24                                   192/24

If this is the case, then you add a static route on m0n0wall to 192/24 
with a gateway of (and be sure to allow incoming traffic from 

However, the other admin MUST also put a static route to 172/24 with a 
gateway of (and add firewall rules if they don't have a 
stateful firewall).

No easy ways here, the other router must be modified or the traffic will 
go to the internet router.
