Hi, This usually happens when a router has 2 routes to the same destination net but one of the next-hops doesn't have a route back to the source.
Whats your routing table look like, how about the destination routers routing table? Is the IP address space on your LAN side public space your ISP provided? How about the interface connecting to them? Also, try pinging with extended commands using your LAN IP as a source and see if that is error-free. If it is, then the destination router has a route back to that IP subnet fine. Do a debug ip packet, might want to point it to an access-list so it doesn't show you everything. eg: debug ip pack 101. If the debugs show everything going out the same interface then it's probably the other end.
