I am trying to ping a Cisco 1601 router with an IP of 172.18.202.249 and a subnet of 255.255.0.0 from an NT workstation on a peer-to-peer NT network. The workstations IP address is 172.18.202.79. I do not get a reply. Yet I can ping the servers IP 172.18.202.250. All are connected to the same hub.

Can anyone suggest what the problem is or how I might troubleshoot it. I've replaced the patch cable between the hub and the Cisco router. I've tried pinging from several other workstations including a Windows 98 station but none can ping the router.

Hi there!
I would check out the configuration of the router:
Is the router interface up and running?
Is there any packet-filtering rules active that makes the router drop your ping packets??
To check this out you will probably need a console cable between workstation and router or a workstation that you can Telnet from.

Hi,
I would agree with TOM, the First thing you do is Check your configuration and ensure that the interface command NO SHUTDOWN has been set after setting the interface you are using. Then try and ping the interface from the console. Also check and make sure that the Configuration on the server is correct and that they have the same Network parameters.

Let us know if you are able to resolve the problem through this means.

Can you ping the workstation from the router...Also check the router's ARP table which will indicate what devices can actually see it from your network
