I have two separate networks, each with their own router and DSL modem.

I have one computer with two NICs that sits exactly in between them.

Is there a way to connect to the other computers on the other network THROUGH this one computer? This computer is a personal webserver with Win2k3 Webserver and is always on.

Help?!

Be sure you read other how-to's on ip forwarding and understand if you really need it.

I read it wrong and answer it wrong too. So get off my case you peanut.

Tcp/ip forwarding will not address your question.
You would need three nics not two in the server, one for each dsl link and one for the lan. Or if one lan and one to the other network the web access would be coming via the other dsl network.

To my knowledge even ISA server can't balance two incoming dsl links.

This is what a dual wan port router can do for you.

I have read that some have been able to accomplish similar with iptables in Linux.

Hmm... three nics? How would that help?

Also, the DSL link for my network is embedded in the router. The other is a separate modem.

I don't want to have to install an extra nic in each computer (and thus have more wires).

Though I do understand how it might work if I rounted MY DSL connection through this server computer and outputted it to my computers on one side... but after that, I still am confuzzled.

I don't want the computers on either network to use the other DSL link either. I have dropped off the 'default gateway' IP address (by manually configuring the IP on the server) to keep the server from using the DSL from the other network.

I want to bridge the networks without running more wires...

You missed the point. Never suggested extra nics in the pcs only the server. Three nics is one for each dsl connect and one for the lan connect.

Make more sense now?

It is unclear why you mention two dsl connections but only want to use one when you already have that setup with your router.

Now if you want your modem access via the server you can engage ICS [better to engage RRAS] between the servers lan nic and the nic connected to the modem.

It is unclear what that would accomplish for you.

You don't really want to bridge the server. See the ip forwarding.

@wanderer

Here is the setup...

Server
Other network- /
DSL modem - router - PC
/ | \
PC PC PC

My network -
* = Same server from above
DSL Modem,router - Gigabit switch - PC
/ | \
PC PC Server*

I want the server to allow the PCs on 'My Network' to access the PCs on 'Other network'

Is this possible? If so, be a little more clear with your explanation, including the IP Forwarding if possible!

I'm not intending on being an idiot... I just am not grasping it!

I am not getting a picture of your configuration.

Let's say you have lanA and lanB. Both haver their own dsl internet connection.

I take it from your first post the server has two nics with a nic in lanA and a nic in lanB.

I took from your post about a web server that it was also a public web server. Is this incorrect and its just a in-house web server?

What lan segment is the server getting internet access from?

It is getting it from My lan... let's call it LanA

And the Webserver is hosting my personal web pages. So it is public.

Oh!

You would need a VPN if you are going out to the web.

I read it wrong and answer it wrong too. So get off my case you peanut.

@Jefro

I know a little (very little) about VPNs... though I would wonder why I would need one.

Continue as to why, please?

Life is love of computing :)

Jefro is suggesting instead of a physical connection like you suggested in your first post you make a logical connection via vpn.

This means you establish a vpn between LanA and lanB by using both DSL internet connections.

Ideally your routers would be capable of doing site to site vpns. I don't see how pcs in lanb can software vpn to lanA. To the lanA server but not lanA pcs. This is where the site to site between routers would accomplish pc to pc access.

This is one option.

Your suggested option of using the web server as a router is not a good one since it is on the internet as a public server. It should be in a dmz or in a different lan segment than your internal network for security reasons.

You would be better off putting a crossover cable between routers and putting both lans into a common subnet so they can communicate. By doing static ip assignments for each lanA and lanB segments you can set the gateway for each to use.
