Need assistance with dual network config

A network configuration specialist is required to assist the OP here:

I found this scenario very interesting as I dabble in networking (which is nothing like "A network configuration specialist"). Of course since I work from home, it is not likely I am going to have TWO 20MB dsl lines, much less one. I am doing good to get 3MB from my home Internet connection.

So how would one connect a web/file server with a dedicated dsl connection to a lan with its own dedicated dsl? It seems that this is not an uncommon configuration.

Here is someone: I am running Windows 7 and using the Cisco VPN adapter to connect to a private network where I access resources starting with the IP address 172....

It seems one way is to create a VPN

Another VPN: how-to-securely-join-two-networks-together-over-the-internet

Here is another one: I'm trying to make it possible to access a webserver on another network (A) from my local network (C). Sound familiar?

I also found this interesting: I used to have a server with 2 network cards, one had a public ip address that can be contacted from the internet and the other card was plugged into the internal network. I found that every 2 hours, when the dhcp lease was renewed on the internal network card, it could change the routing i had set up until i started using "-p"

I also found a TechNet article using netsh commands to "To add a persistent static route to the “Local Area Connection” interface, type:"

Wish I had more time (and resources) to play with this...

Take all the time you need.

I am running 2 network sources. I have a DSL line that connects to the phone line with a modem from the modem to a router from the router to a switch where my network computers connect and my printers connect. I also have a much faster wireless connection from another provider which runs from the antena on the roof into a radio reciever and from there into hte same switch box. This computer is set to use the DSL line one by setting the address from the provider thee computer next to it on the same home network is set to use the wireless connection by setting a different network address. Think I got it I had help setting it up from the wireless provider for using my roof as a site for one of his antennas. All computers can see each other yet use different internet providors. All computers can print to the network printers. Windows 7 prints to usb printers on xp machine. The advantage is the upload speed of the wireless connection is 3 gigs it screams compared to 250 mgs up for 1 gig down on DSL. Think I got that right. I can send my photo files out with out shrinking them to far. Limiting factor is on person I send them to.

Sorry that was so long winded. I will try to answer questions. What I have works.

Okay how is your network setup?
do you have a dual wan router? two single wan routers?
does the wireless connection run straight to your pc?
A visio drawling, or even a quick paint sketch would be great.

Here goes wireless network on my roof comes into the house from there runs by network cable to a switch, total of 8 network cables run into it. From the switch. It runs to a monowall router, from monowall router into modem from dsl line. dsl is connected to phone. Mono wall router is I think splitting signal. Or enabling (to) 2 networks, It is also capable of wireless signal to laptop, I am using 2 ip addresses set in monowall router. Anntena on roof is power over internet. Please keep asking the questions I will keep trying. I will try to draw a diagram with all parts labeled in morning. There are 2 mesh antennas on roof with a flat panel also. but for simplicity what ever happens up ther is only connecting to the wireless network. from there a single cat 5 cable is connected to the switch. The switch connects to the monowall router, monowall connects to DSL modem. Modem to phone line.

I am able to also pick up the wireless signal from the array on my roof with my laptop depending where I am in the house , a metal roof shields some of the signal.

Please draw up a small drawing in paint so i can have a visual.
Its easier for for me to see that way.
I will try to figure it out without for now

To make sure I am reading this correct, Your wireless come in and goes to a switch. then connects to a router that has your dsl connected to it as your wan.
To separate the connections you are using two separate v-lans.

May I ask what exactly are you trying to setup?
I may know what your trying to do, Are you just trying to set win7 up the way it was before?

Not sure drawing it will show anything. If I say one network cable cat 5 comes from the antennas on the roof, an IP address or addresses, it connects to a normal 8 port switch or hub, 8 cable imputs, from my other computers and network printers. It just splices the cables together. From the switch 1 cable cat 5 runs to the monowall router, which is a dual router, it also has a rubber duck antena for wireless connection. From the monowall a single cable runs to the modem supplied by my DSL carrier another IP address, from there to a phone jack. It is the monowall router that enables 2 sourses. I am not using vpn or tunneling at all.

Both my computers at my work station are connected by cat 5 cable to the switch/hub, my system is working fine.

rereading your last post, think we have been playing tag on a problem niether one of us have. I thought you wanted to set up system using 2 different internet sources. My system works. I was trying to describe what I was doing. Thanks for the help. questions keep asking and I will keep trying to answer them.

It is pretty simple if you have a router capable of connecting to multiple networks (not just two), and you have either have one server with two IP addresses, or two servers. It is then a simple tasking of forwarding the public (internet) IP addresses to there respected local network IP addresses. The services then listen to any connections from one or the other IP addresses (or even both).

* Might also be possible to do it with a two routers and a switch. This approach will most likely require two separated subnets.
