TCP/IP set up
JAnderson Sep-05-00 02:15 AM
I am trying to share my new Cable modem over my LAN with my other computer. My LAN has worked fine for a year. In following the Sygate setup pages, I find difficulty in getting the TCP/IP working properly.
Server uses Win95b
Client uses Win 98
Server running Zone Alarm firewall
Server can ping www.Sygate.com, but not Client.
Client can not ping Server.
In sygate Manager, Client "sees" both computers and lists their TCP/IP setting etc.
In sygate Manager,Server only "sees" itself, not the client machine.
The LAN continues to show both computers when double clicking Network Neighborhood.
The Sygate Diagnotic program appears to think that all is well on Client.
Sygate Diagnostic says TCP/IP is fine on Lan when run on Server, but says "checking TCP/IP...."on NIC used by Cable modem.
I have removed and added TCP/IP to both LAN cards
but have not done so to card used by Cable modem, since Sygate pages indicate not to mess with a working Cable modem card.
I emailed Sygate last week but as of yet, no response.
Thank you
Jim

If you are using dynamic IP addresses (default), try running (Start, Run) winipcfg, select the adapter, and release and renew the lease of the IP address from SyGate's DHCP server. If you are using static IP addresses, disable SyGATe's DHCP server. Also, I would temporarily remove the firewall in case that is causing the problem. SyGate acts as a firewall. Larry

Thank you very much for your response.
In trying both of the sugestions, my situation remains the same. I released and renewed "all" leases. (Is this just a matter of clicking on the "release" and "renew" buttons in turn? Then I disabled Sygates DHCP server amd removed my Zone Alarm firewall

Dont I need to get both my computers able to successfully Ping each other to verify TCP\IP is configured correctly?. They are unable to successfully ping each other, although the Server is able to ping www.sygate.com. The Sygate diagnostic program indicates the TCP\IP "passes" on the LAN card in both computers. But yet...no ping between them!
Thank you
Jim

Yes, you must be able to ping the host from the client. Is the net mask set to 255.255.255.0 on the LAN adapters for both computers? Can you ping 192.168.0.1 (host) from the client? Can the client ping 216.92.56.121? Can it ping duxcw.com? If it can ping 216.92.56.121 and not duxcw.com, you have a DNS problem. 216.92.56.121 is duxcw.com. I am calling it a night. 1:34 AM here.

Hi Larry,

Yes, the net mask is set to 255.255.255.0
Pinging from the Client:
unable to ping 192.168.0.1
yes, able to ping 216.92.56.121
no, unable to ping duxcw.com

Pinging from the Server:
Unable to ping 192.168.0.2
yes, able to ping 216.92.56.121

The complete listing of both computers network settings are as follows:

***Server network settings:***

The client DNS should be enabled and set to 192.168.0.1. Looks like you are using static IPs. If so, disable the DHCP server in SyGate. You may want to set-up host tables per C:/windows/hosts.sam (sam = sample file). I would get rid of the Family Logon. What are the computer network names? If the names are numbers change them so they are not. Larry
