2 connections and the 2nd cancels the 1st, what to do?

Hi,
There's a computer connected to Internet and a network printer via a
router (so the computer is connected to the router that gives access to the
printer and the internet). This computer also connects regularly to a
business network using a modem (by phone). I think it's a VPN but I'm not
100% sure. The problem is as follow, the modem connection cancels the router
connection as a result, no internet connection anymore and unable to print
while connected using the modem.

Is there a way to tell Windows that one connection must always remain even
when the modem is connected?

Thanks a lot

I'm not a VPN expert, but I suspect what is happening is that when you
perform the dialup connection, you establish a VPN tunnel to your business
network. This causes a new route to be placed in your machine's route table
that takes precidence over your default gateway. So in effect, all traffic
gets sent to the remote network through the VPN server (internet, local and
remote).

If the DHCP server is W2K3 based, there is an option called "Classless
Static Route Option". This allows remote access and VPN clients to perform
split tunneling when connecting to remote networks. So essentially then you
can configure it so that traffic destined to the internet (or printer for
that matter), will route correctly.

However, I believe there are some security considerations around this.

See
http://www.microsoft.com/resources/d...tr_vpn_how.asp
and look at the VPN Addressing and Routing Section.

Charles Denny

The other alternative is to add a static route to the client machine so
that it has its own specific route to find the printer, rather than rely on
default routing. If you do this, the client should be able to find the
network printer even if its default route changes.

And How can I do this assuming the Client machine is on Windows XP? Must
this route be set on the client machine?

First up, you need to know what subnet the printer is in and what router
it uses to get there.(This router address is probably the client's current
default gateway setting). If you know that info, you use the route command
to add the routing info to the client machine. Type the command "route ?"
at a command prompt to see the syntax. The command you need would look
something like this.

route add -p 192.168.21.0 255.255.255.0 192.168.1.1

where 192.168.21.0 is the target subnet and 192.168.1.1 is the router
address.

Why not just disable the "Use Gateway on Remote Network" in the Modem
Connection's Advanced Properties?,...since that is what caused the problem
in the first place. It doesn't matter if it is VPN or not, a dialup
connection is still a dialup connection and works on the same principles. By
default, when a dialup connection goes "active" it takes over and becomes
the "default route" unless the above item is disabled.

Hi Phillip,

That works fine, as long as the subnet route he then gets (instead of a
default route) for the VPN connection covers everything he needs to "see"
across the link!

In fact, this option is not availlable, because the connection is done by a
third party program and not by the Windows default connection system. The
third party program does not provide this option, so we have to go another
way. but thanks for the trick, It'll be useful with other cases...

Thanks a lot
