Simultaneous Dial-up and DSL Connection

G

Guest

In my home office I have a DSL connection that my desktop computer uses for
Internet access. My desktop is also equipped with a 56k modem, which I have
recently begun using for dialing in to my company's network for our corporate
email. I also share my DSL connection with other PC's on my LAN via Internet
connection sharing. I am the host PC for internet connection sharing. I use
Windows XP Pro.

The problem I've been having is that whenever I use the modem to dial into
my workplace, I lose my broadband connection. To make things worse, my
dial-up connection is only for retreiving emai and cannot connect to the
internet. Thus when I dial-up I lose access to other internet sites. When I
disconnect the dial-up session, the broadband connection is automatically
restored.

Is there a way to use these two connections simultaneously, where the
dial-up is used solely for retreiving email and all other internet needs via
the DSL connection? Is it also possible to share both connections
simultaneously over LAN?

As long at this does not violate your company's policies, you may be able to
achieve the result you are looking for by disabling the default gateway for
the dial-up connection and then manually creating a TCP/IPv4 route to your
company's email server after each time you dial. Here's how:

Disable Default Gateway:
1) Open your "Network Connections" folder
2) Right-click on your dial-up connection and choose "Properties"
3) Switch to the "Networking" tab
4) Select "Internet Protocol (TCP/IP)" and click on "Properties"
5) Click on the "Advanced..." button
6) Uncheck "Use default gateway on remote network"
7) Click OK 3 times

Manually Create Route:
1) Connect to your dial-up connection
2) Open a cmd window:
a) Click on the Start button and choose "Run..."
b) Type in "cmd" and click OK
3) Use the ping command to obtain the IP address of your email server:

ping [name of email server]

Example:
ping acmemail01

4) Use the ipconfig command to obtain the IP address for your dial-up
connection:

ipconfig

5) Create the route for this dial-up session:

route add [first number of email server IP followed by ".0.0.0"] mask
255.0.0.0 [IP of dial-up connection]

For this example, we will assume that you have the following IP addresses:
Email Server: 172.60.12.32
Dialup Connection: 10.45.158.44
Example:
route add 172.0.0.0 mask 255.0.0.0 10.45.158.44

6) Close the cmd window

Now all of the network traffic destined for your email server (or any other
servers on the same general network) should go over your RAS connection, but
everything else should go over your broadband connection. Hopefully this
will also prevent your dial-up connection from interrupting your ability to
share out your broadband connection to your other computers at home.

One more thing, it seems that the settings are lost once the computer is
restarted. Is there anyway to make the route add permanent? Thanks in
advance.

Hi:

1. I would love to have your configuration! I have been trying with all
stunts to disable the lan when i connect through the dialup.
What are your dialup settings? And lan - what is enabled/disabled

2. To answer your question,

route -p add 172.0.0.0 mask 255.0.0.0 10.45.158.44

Regards
