guru question, part II

[Z24]

I posted a while ago and got an answer. link Everything seemed to be working.

The problem now is that when that machine dials out to the internet, it disappears from the network. Is there any solution to this?

 

[Z24]

The setup is as below, but the workstation has a modem in it. When it connects to the internet, it disappears from the network. How can I fix this?




Server has 2 nics, eth1 and eth2
eth1 gets IP 10.0.0.1 Subnetmask 255.255.255.0 and is connected to the hub
eth2 gets IP 10.0.1.1 Subnetmask 255.255.255.0 And is connected via crossover cable to the Special workstation

Special workstation gets IP 10.0.1.2 Subnetmask 255.255.255.0 gateway 10.0.1.1

All other workstations get IP 10.0.0.2-10.0.0.254 Subnetmask 255.255.255.0 gateway 10.0.0.1 and connect to the hub

Then to enable the Special workstation to see the rest of the network, on the Server hit Start -> Settings -> Control Panel -> Network -> Protocols -> TCP/IP Properties -> Routing -> check IP Forwarding.

I would disable "USE DEFAULT GATEWAY ON REMOTE NETWORK" in the TCP/IP settings in your DUN connection. Also, I take it that these machines are Windows NT 4?

 

[Z24]

Yes, both machines are NT 4--one is Server, the one with the modem is Workstation.

Try my suggestions first and see what happens. After that, let me know. 🙂

i'll check back in tomorrow after i've had a chance to try it. thanks.

With "Use Default Gateway on the Remote Network" CHECKED,
I can access my internal network until the workstation connects to the internet. At that point, I can't even ping an IP elsewhere in the building. As soon as I hangup the internet connection, I can access the internal network again.

With "Use Default Gateway on the Remote Network" *UN*CHECKED,

I can access my internal network all the time. Unfortunately, I can no longer access the internet.

There has to be a solution to this....

AHAH! I solved it!

I added a static route by doing:

ROUTE ADD 10.0.0.0 MASK 255.255.255.0 10.0.1.1 /P

And it works!!
