Well, I'm having trouble visualizing your network.  This is what I
invision at the moment:

ISP(213.250.143.241)---BigRouter(213.250.143.242)
		        |   |   |_Office(172.16.16.1)
			|   |_Web(172.16.8.1)
			|_Service(172.16.4.1)

Based on this, the default route on the BigRouter must be to
213.250.143.241 and not 172.16.16.254.  

The other, as you mention, you must be doing NAT on the BigRouter for
the 172.x networks.  The problem with using the Office network for
Internet access is that it doesn't have a legal address to use for
sending traffic to the Internet.  It can't traverse the 172.16.16.0
network to the BigRouter to get to the Internet unless you have a
tunnel between the two routers using legal addresses.

Also, if the Web router has a default route to the BigRouter, you may
have a routing loop.

Let me know if the diagram is off.
