I've spent the last few days researching exactly how to accomplish my networking task, but I haven't found an exact solution. I'm trying to network three pc's (with the option of one more) and two of them have dedicated dsl connections. My main pc is out of PCI slots, so I ordered a dual-port Intel 10/100 NIC card (pulled from a Dell server) to replace the single port NIC already in there. I just ordered everything I need (or think I need) for this networking project yesterday, so all the equipment should be in this week. So, here's the setup:


PC #1


Dual-port Intel 10/100 NIC

Westell 2100 DSL modem with dedicated 3Mbps connection (static IP)

WinXP Home


PC #2


Two seperate 10/100 NIC cards

Westell 2100 DSL modem with dedicated 1.5 Mbps connection (dynamic IP)

WinXP Home


PC #3

Single 10/100 NIC card (no dsl connection)

Win98 (It can be upgraded to WinXP Home if it would help)


Linksys 5-port ethernet Workstation switch


Here's what I want to do:


PC #3 share an internet connection with PC #2 (PC #3's 3Mbps left alone just for it)

All 3 PC's share files/folders/drives...basically full access to all three PCs

PC #1 to be able to fully control PC #2 (like remote access)


Basically, I want PC #1 to use it's internet connection by itself, nothing able to take from it's 3.0Mbps of bandwidth. But I also want PC #1 to be able to tell PC #2 what to dl/ul from it's own dsl connection, which later the file(s) can be moved from PC #2 to #1 over the network.


PC #3 just needed internet connection, so I want it to share with #2.


Confusing? Any help on how to connect all these PCs and what software I need to use would very much be appreciated.


P.S. I know I started a thread on this a few months back, I just finally got off my butt to do it.


Thanks again.

Well if I understand your problem it shouldn't be too hard to setup. In fact the default way windows handles routing IP traffic should take care of it. Simply attach one DSL line to PC #1 via one card and the other to a hub or switch that PC #3, and PC#2 are connected to. Then if you can attach the other DSL line via a home router to the hub.


Then on computer #1 set the default gateway to be the DSL line if it doesn't automatically do it for you. Thus any traffic destined for the Internet should travel via the DSL line from PC#1 and local traffic will go over the other NIC to PC#2 or PC#3. And PC#2 and PC#3 should both utilize the other DSL line for internet traffic.


If you can't utilize a router it gets a bit more complicated because you will need to setup PC#2 for connection sharing or something similiar. And may need a third nic in PC#2.

PC1 - NIC port 1 to DSL configured with default gateway of DSL IP (not familiar with the modems (are they external?), NIC port 2 to the switch with default gateway to your internal IP range. Ensure in "Network Connections" that "Bridging" is NOT selected.


PC2 - Nic port 1 to DSL, default gateway set to whatever DHCP gives you.

Nic port 2 to switch same as PC1. Run the ICS (internet connection sharing wizard) and share the DSL connection.


PC3 - NIC to switch and run the ICS connection client and point it to PC2 (PC3 will be setup to obtain a DHCP address from PC2).


I'm not sure if XP Home supports this however.


What I would do myself at any rate is (provided the DSL modems are external) purchase a DSL/Cable router (they'll have a 4 or 5 port switch built in) connect PC1 as above and setup PC2 and PC3 to the router. Then block outbound traffic from the INTERNAL IP of PC1 son that PC2 & 3 are the only ones on the 1.5mbit connection (or don't block it and PC1 will have internet on both connections and all PCs can talk away).


If the modems are internal that kinda' restricts you to option 1.

The Westell dsl modems have built in routers, so I think I'm ok. The way you guys explained how to hook it up was what I thought, though I wasn't sure if PC #1 being connected to 2 different internet sources would screw it up.


Now, for PC #1 to remotely control PC #2, do I need to use something like Radmin? I have Radmin working on PC #1 since it has a static IP, though I can't get it working on PC #2, since it has a dynamic IP. I even tried signing up for no-ip.com and still can't get it to work.


Thanks for your help!

PCs 1 and 2 will have 2 IP addresses each, one internal and one external. What you need to concern yourself with regarding remote administration is the internal addresses, not the external ones.

Yep, just figured that out! Thanks again.

well i have a networking problem that doesn't make sense. I got the dsl running to the router and the router is wired to 1 computer and the other computer is wireless. Both computers can access the internet, however i have spent many hours trying to file share and its not happening. What im i not doing?

same --workgroup-- name ?


is file/printer sharing checked ?

Check the WinXP firewall settings as well. By default the Windows firewall allows outbound traffic but blocks all incoming traffic. With SP2 it's on by default.
