Internet going through the Server rather than

August 24, 2011 at 09:35:02
Specs: Windows XP
We had every PC has direct access to the internet and after our renovations (adding more workstations) now every PC has to access internet through our Server.
This caused a great deal of problem because everytime the Server down, nobody can access internet.
We did not setup any proxy or anything else.
Any ideas will hepl.
Thanks, folks.

Click START / RUN / CMD to start command prompt.
At the command prompt, type in ipconfig /all and check whether the setting for the default gateway.is correct.
If not, check the configuration of your DHCP server for the default gateway address.

Hi paulsep
thanks for a quick reply.
i checked that before, ipconfig, release, renew and the deafault gateway is the Linksys router 192.168.1.1 for all of the PC's in the office and so is for the server.
Yet the internet access is still going through the server.
any more ideas?
thanks so much.

According to the above information, external traffic can not be flowing from clients, through your server, and out to the internet.

What is making you think all internet traffic is flowing through the server?

Here's a quick run down on how traffic flow works.

Within the LAN, a Default Gateway is not needed. Every computer that's properly configured and on the same network can communicate with every other computer on the same segment (assuming all are correctly configured).

Whenever local traffic needs to pass through a beyond the local network to another network, then you need a "gateway" device.

In your case, your clients wish to access the internet. Your SOHO Router is your gateway device between the internet and your LAN. The LAN side of your router is assigned the following IP address: 192.168.1.1 as stated by you. Thus, all client computers wishing to access the internet need that address as the "default gateway" IP in their TCP/IP settings. That way when traffic needs to pass outside of your LAN, it knows where to go (ie: it goes to the gateway device which then handles it from there).

In order for all LAN traffic to flow through your server and then onto the internet, all clients would have to have the server's LAN IP as their default gateway address.

Hi Curt R
"What is making you think all internet traffic is flowing through the server?"
When I disconnected the Server from our switch, nobody can access Internet.
There is no proxy setup on any PC.
Admin people said they never did cahnge anything in the Server's User account.

"In order for all LAN traffic to flow through your server and then onto the internet, all clients would have to have the server's LAN IP as their default gateway address."
For the above comment, I checked every PC a couple times to make sure the default gateway is properly set (SOHO router and not the Server's IP).

Thanks so much for your help.
Anything I can do to make it works again, yes it was working before.

That's uniquely strange.

No client has the server's IP as it's default gateway, yet when you shut it down, they lose internet connectivity.

If it were me, I'd start by verifying all the DHCP settings on the router (ie: DNS and default gateway should be the LAN IP of the router). Then I'd shut down the server and reboot a client and see what happens once the client has rebooted.

Things to check from the client:
- Did it get proper TCP/IP settings from the router's DHCP server?
- Can you ping the default gateway IP?
- Can you connect to the router's management interface in a web browser (via the default gateway IP)?

If those are working then you should have internet connectivity on the client. I would then try pinging external websites to verify.

Make sure the DHCP server on the server itself is disabled.

Check your TCP/IP settings on the clients. Is their DNS address the server or the router?

If the server, then that would explain why the clients lose internet connectivity. Without DNS, they can't resolve external websites.

If you're not running an active directory based Windows domain, clients should get the router's LAN as their DNS (and default gateway).

If you are running an AD integrated domain, add the router's LAN IP as another DNS server address. Put it below the DC's IP in the list so each client always attempts to resolve through the server first.

we need to see the results of a ipconfig /all from a workstation and the server.

Is your server running Active Directory?
