Unable to ping different subnet
Posted on 2010-01-06
I am having a issue with a company that has three office locations, two of them are linked together via fiber with a vlan. The IP scheme is 10.0.0.0/24 for those two offices, but at their third office it is connected via microwave and is on a different subnet of 10.0.2.0/24. I am able to ping the internal IP of the router at the microwave site just fine, but when I try to ping the machines with the exception of one I am unsuccessful. Where the problem does not make any sense is I can ping one of the client machines within that network but not the other two. But I can also VNC to any of the machines in this microwave network.
There are routes in place, and have been in place for years and have worked fine. I have already added static routes to the server that I am attempting to ping from, and I am still unable to. I have spoken with the ISP and they said that there are no problems for what they can see. The topology on the microwave network is that when data is received it passes through a cisco router and then through a switch to the client machines. The client machines are able to ping the server they are trying to reach just fine, but from the server I am unsuccessful. Right now the prime suspect is the Cisco router at the remote location. Any ideas?
