ping to outside of lan

Our lan is connected to outside through a broadband modem. How can Ping to outside ip address from Win 98? I know it can be done from Win 2000.

 

Hi, thank you for your reply.
I had always tried this way, but it came out "time out" message. It works on Windows 2000 after setting the gateway, but it can't work on Windows 98.

 

You state "after setting the gateway ", I'm assuming that the Windows 98 machine is not in fact directly connected but goes through another machine.

Check the DNS on the 98 machine, you can either use ipconfig /all command in a DOS session, or run the GUI version winipcfg using Start -> Run.

If the DNS is not the gateway machine then you wont have access.

 

Just a thought... But if there is a firewall or other security measure on the network than it could be configured to block ping requests (also called ICMP requests) this could cause the request from timing out.

 

Hi all,
Thank you for your reply.
I'm sorry that I didn't describe the detail enough.

As I indicated in the first time, our LAN is connected to the ISP through a ADSL MODEM/Router. The Router is connected to our Ethernet hub. Our internal IP address (192.168.xx.xx) is invisible from outside. Once the MODEM is connected to the ISP, it is assigned a IP address (202.xxx.xx.xx) by the ISP. There is no DNS server in our LAN, we use the DNS server of the ISP. There is no problem to access internet or email.

In Windows 2000, after setting the gateway to the Router's internal IP address(192.168.xx.xx), it can Ping to outside.

In Windows 98, it seems that we can't set the gateway. After setting the gateway and restart, check by IPCONFIG, the gateway is still blank.

Here is the error message in Windows 98:

Pinging 202.79.64.21 with 32 bytes of data:

Destination host unreachable.
Destination host unreachable.
Destination host unreachable.
Destination host unreachable.

Ping statistics for 202.79.64.21:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms

The reason I ask this question is that we need run an application to access our remote database.

Thanks again.

 

Uninstall and reinstall TCP/IP on the Win98 client. Setting the gateway should work as you expect.

You can set a default gateway at a command prompt using (lost when you reboot):

route add 0.0.0.0 mask 0.0.0.0 192.168.x.y

To view routes:

route print

To delete the default route:

route delete 0.0.0.0
