it really depends on how your LAN and DMZ are connected, please advise the details of the router in the middle and the configuration if available.

commonly, that is just a firewall rule to enable at least one way communication from the LAN to the DMZ.

I would also look into the routes between those two networks and also make sure there is the trusts in the interfaces on the firewall between those two as well.  Once that has been confirmed, then check the firewall rules on if the ports are allowed out of your 172. network to the DMZ and the DMZ is set to even listen to the requests

as i mentioned above, your router between LAN and DMZ should be properly configured to allow at least one way (LAN -> DMZ) communication. a routing table item and a firewall rule are required.

do you have access to the router between LAN and DMZ?
