i'm still new in this area, but you may need to add a routing table entry that tells the router what gateway to send information out of to reach a non built-in route. Basically, you'd need to add the routing table entry on the remote network's router to the office's router
The correct way to handle this problem would be to change the subnet mask of the remote office from /16 to /24.
However, if this is not a viable solution for now and you need to access specific resources located at the office network, a simple static route on the workstations located at the remote office, will do the trick.
For example, let's say you need to access a file server at the office network with ip address 192.168.0.10. If you enter the following dos-based command at a workstation, you should be able to see the file server:
I try to add a static route on the pc in the remote office, but i recieve an error:
[code:1]route add 192.168.1.0 mask 255.255.255.0 192.168.3.3 metric 1
The route addition failed: The parameter is incorrect[/code:1]
