How can I disable IP routing in win98se?

My home LAN looks like this:

dsl modem---router (486---hub---PC1
           running        | '---PC2
            floppyfw)     '-----PC3

The 3 PCs share a static IP. They all have 3com 3c509b network cards, which are configured the same way in Control Panel->Network->TCP/IP. Internally, they all recognize each other in Network Neighborhood and can transfer files among themselves. At some point before getting DSL, I had used the Home Networking Wizard to connect them internally. I don't know whether or not that is a factor in my problem.

PC1 will not connect to the Internet. When I try to surff, I get one of these messages:
"Cannot connect to remote server", or
"Connection closed by remote server."

PC1 is a dual-boot machine; under Linux, it connects fine.

I know of only two differences between PC1 and the other two machines:

1) ZoneAlarm is installed on PC1. However I have tried shutting down ZoneAlarm and it made no apparent difference.

2) "winipcfg" shows that PC1 has IP routing enabled; the other machines do not. I suspect that this is my culprit. I don't know *how* it got enabled. Can anyone tell me how to disable it?


(ps - the point value does not reflect my sentiments, but I'm new here and only have 90 points to work with)

My little diagram got screwed: the router's a 486 running floppyfw and PCs 2 and 3, like PC1, are connected to the hub...

First thing to check is PC1's default gateway.  It should be the same as on PCs 2 & 3. (

ipconfig at a dos prompt will tell you what it is.

Having routing turned on shouldn't prevent it from being able to browse the web.

98 ip routing is off by default, and only enabled by installing ICS or a reg hack
EnableRouting=1" in the HKLM\.....\Vxd\MSTCP registry key

The gateway (for all 3 PCs) is

I found the "Enable Routing" entry in the Registry and changed it form "1" to "0". No apparent effect.

Any other suggestions, anyone?

did you reboot?
if so, then the ip routing was not the issue
what happens when you ping
start with the local ip, then the gateway and finally here

Yep, I rebooted after editing the Registry.

Will try pinging when I get home this evening. (I'm assuming that to do so, I go to DOS prompt and type "ping <IP address>"?)

Yes, that is how to ping

Pinging results from PC1: - ok (i.e., all packets received) - ok (gateway) - request timed out

Changes in results with Linux on PC1 and with PC3 made me suspect a hardware problem with the 486 router/firewall machine, so I replaced it with PC2. After that, I got these ping results on PC1: - ok - ok - ok - ok

The dns entries for PC1 and PC3 are the same.

The answer was accurate; as it turns out, my question was not, and my problem persists. Sigh. I'll try to construct a better question, with more data.
