Using 2 NICs to route across two LANS

By greenergrass ·
Hi,

I have an ADSL modem (router) with a fixed IP address of 192.168.254.254 which I need to access from PCs on my LAN IP range 192.168.1.0.

I have put 2 NICs into one PC one NIC has the IP 192.168.1.105 and one has IP 192.168.254.253.

I can access the router from this PC.

I believe that there is a way to make WIN98se route my LAN onto the ADSL Modem using the two network cards but cannot make it happen. Could someone give me step by step instructions please

This is not step by step, but on the PC with 2 NICs, you need to enable routing (known in Windoze as "IP Forwarding", I believe). This will turn that PC into a router. Your PCs on the 192.168.1.0 network will need to use 192.168.1.105 as their default gateway.

And that'll work.

I have tried doing that already. This enables me to ping the NIC 192.168.254.253 but not 192.168.254.254.

What Gateway/DNS settings do I need to put onto the NIC on my LAN PCs with IP range 192.168.1.0

Thanks

You can try using Microsoft ICS (Internet connection sharing). Another possibility is some other third party software. I have not used ICS, but I have used a product called Winproxy (www.winproxy.com) and it is a very simple installation. A 3 userversion is $60, you can get a free trial version at the web site

All devices on the 192.168.1.0 subnet need to have a default gateway of 192.168.1.105. The dual-homed device needs to have a default gateway of 192.168.254.254 (the ADSL modem).

I don't believe Win98 will route natively but as a previous poster said you can use ICS or WinGate or some such software.

Hope that helps -

You can also enter the router setup and resolve many conflicts there by establishing your requirements there.

Unfortunately, you cannot do what you want with the 98 OS. While you can set up a Win98 machine with two NICs, you will be unable to get 98 to act as a router (ie, pass IP traffic from one subnet to another). For this you need NT, which has the Routing and Remote Access Service and allows IP Forwarding. Your best bet is to enable Internet Connection Sharing.
