Hello Mike,
To help you out the routing entries in the router itself would be very helpful.
As always with TCP/IP "one has to know the way back _and_ forth" ... ;-)
As Chris already stated, especially routers that perform some kind of firewall
functionality at their software level, normally have ICMP echos disabled, after
testing/implementing phase is completed. This is for additional security 
reasons.

HTH and regards from germany, Philipp Rusch
