Connect to Multiple Networks (Simultaneously) From Same Computer

Charles Law · Apr 23, 2008

I'm not sure if this the right place, so please redirect me if there is a
better place (I looked but none was obvious).

I have a laptop that uses a dial-up connection to a secure network (the only
route in). I also want to be able to connect to another remote network from
the laptop, at the same time, via broadband.

So far, all attempts have failed. If I hang-up the dial-up connection, I can
see the internet, but once the dial-up is connected all I can see from the
laptop is my local network (and the remote secure network, of course).

The laptop has a wireless connection to my local network, and when I look at
the properties there is a place to enter "Alternate Configuration", but I
can't get that to make any difference.

Please can anyone suggest how I might do this?

TIA

Hello Charles,

Did you try with Remote Desktop over the broadband connection?

Re: Connect to Multiple Networks (Simultaneously) From Same Computer

Hi Meinolf

Thanks for the reply. I haven't tried RDP except over the dial-up
connection. What I have tried is pinging my remote network IP when dial-up
is connected and I get an instant reply from the secure network (over
dial-up) saying that the host is unreachable.

It seems that all traffic is sent down the dial-up path, whether it can be
reached that way or not.

What I think it needs is something to route only private network traffic
down the dial-up path and everything else through my local gateway, but I
can't see where I might set that.

Re: Connect to Multiple Networks (Simultaneously) From Same Computer

Hello Charles,

Maybe you can try to add a static route to the broadband gateway for the
network you are trying to reach. But i think you will not be able to connect
to 2 different networks simultaneously, so waht is the reason for this kind
of configuration?

Re: Connect to Multiple Networks (Simultaneously) From Same Comput

More info needed.
I assume you are DHCP client of whichever network you successfully connected
to last. Correct me if you have a different set-up.

Post results of 'route print' when you are
(a) connected to secure network via dial-up
(b) to your broadband network

Our offsite users can access our network (via VPN) and their local printers,
and see Internet via their ISP, not ours, by using a set-up called 'split
tunneling'.
I suspect this may only work for you if you put your dial-up modem on local
Ethernet so that you access both networks via same interface.

From your description I'd assume you are using a VPN connection. If not, you
can ignore this post...LOL. Be aware that many VPN programs will
specifically disable all other network connections while the VPN is
connected to its parent network.

What VPN client are you using? Any chance it was provided by a cell carrier
and/or your corporate IT? These type custom VPN clients are notorious for
this behavior. It is by design.

Re: Connect to Multiple Networks (Simultaneously) From Same Computer

Hi Frankster

There's nothing special running on the laptop. I am just using RDP to get to
the secure network. That works ok, but whilst the dial-up connection is
open, all non-local traffic seems to go to the secure network, and nowhere
else.

Re: Connect to Multiple Networks (Simultaneously) From Same Computer

Hi Meinolf

We support our client using RDP onto their network. At the same time, we
have our own servers elsewhere, that we access via the internet, and that we
need to get files from for the secure network at our client's.

I can go to another machine, and transfer the files to our local network,
and then back on the laptop I can pick them up and transfer them to the
secure network. It is just a bit tortuous having to do it in two steps, and
of course takes twice as long.

Re: Connect to Multiple Networks (Simultaneously) From Same Comput

Hi Newell

The laptop is a DHCP client on the local network, and to the secure network
when connected.

What do you mean by the route print? I can't post anything that explicitly
relates to the secure network, for obvious reasons.

It sounds like your off-site users do exactly what I want to do here. I
wonder if I use the laptop just as a gateway to the secure network, and
allow ICS that would do the trick? The problem would be that Windows always
wants to set the IP on an ICS machine to 192.168.0.1, and that is the IP of
my router.

Re: Connect to Multiple Networks (Simultaneously) From Same Computer

You didn't really answer the question about what remote access client you
are using.

Many remote access clients will prevent access to other networks. Some,
such as the Microsoft dialup client, don't prevent it but it is disabled by
default. You can change this in the dialup connection properties.

If you are using this client, see KB 254231 .

Re: Connect to Multiple Networks (Simultaneously) From Same Comput

Re: Connect to Multiple Networks (Simultaneously) From Same Comput

Here is the result of 'route print > C:\rprintlog on my XP workstation:

===========================================================================
Active Routes:
Network Destination Netmask Gateway Interface Metric
0.0.0.0 0.0.0.0 192.168.1.200 192.168.1.220 10
127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1
192.168.1.0 255.255.255.0 192.168.1.220 192.168.1.220 10
192.168.1.220 255.255.255.255 127.0.0.1 127.0.0.1 10
192.168.1.255 255.255.255.255 192.168.1.220 192.168.1.220 10
224.0.0.0 240.0.0.0 192.168.1.220 192.168.1.220 10
255.255.255.255 255.255.255.255 192.168.1.220 192.168.1.220 1
Default Gateway: 192.168.1.200
===========================================================================
Persistent Routes:
None

This maps the entire IP address space to an interface (192.168.1.220 is my
ethernet card, 127.0.0.1 is a loopback to to the TCP/IP input of my PC) and a
gateway (192.168.1.200 is a DSL router connecting to our ISP).
So all loopbacks (127.x.y.z) and traffic for 192.168.1.220 originating in my
PC never gets out onto our Ethernet LAN.
Traffic for our LAN (192.168.1.x) is broadcast from my ethernet card, as are
a few other special cases.
Any other address p.q.r.s is sent to the DSL router.

This table is set up by the DHCP server on our LAN when I log on - it
assigns my IP, my net mask (defines size of LAN), and my gateway.

192.168.x.y are un-routable addresses - traffic for them will not pass
either way through a router, so they are secure - our LAN speaks only to our
LAN, yours speaks only to yours.

This should be enough info to allow you to diagnose your rote print outputs,
or ask intelligent questions if you don't want to divulge the IP of the
access point to your secure network.

Re: Connect to Multiple Networks (Simultaneously) From Same Comput

Hi Newell

Thanks for that. I will compare it to our own here and see what sort of
differences it throws up.

Cheers

Re: Connect to Multiple Networks (Simultaneously) From Same Comput

Ok, my list ends like this:

255.255.255.255 255.255.255.255 <secure network gateway> <secure
network gateway> 1
255.255.255.255 255.255.255.255 192.168.0.3
2 1
255.255.255.255 255.255.255.255 192.168.0.3
192.168.0.3 1
Default Gateway: 192.168.0.1

Is that normal? Could that be the problem?

Re: Connect to Multiple Networks (Simultaneously) From Same Computer

Hi Bill

I am using the Microsoft dial-up client, but I have already unchecked the
"Use default gateway on remote network" box, but I still cannot get out onto
my broadband connection through my LAN when the dial-up connection is open.

Re: Connect to Multiple Networks (Simultaneously) From Same Comput

Re: Connect to Multiple Networks (Simultaneously) From Same Comput

It's the 0.0.0.0 route that gets you out to the internet.

From reading your comms with Bill Grant, sounds like you are not using the
remote gateway of your dial-up connection, but 192.168.0.1 which I guess is
your broadband router.

So what are the two 0.0.0.0 entries in the case of (a) dial-up connected
(b) dial-up not connected.

Re: Connect to Multiple Networks (Simultaneously) From Same Comput

Re: Connect to Multiple Networks (Simultaneously) From Same Comput

The 0.0.0.0 entry, connected is

0.0.0.0 0.0.0.0 192.168.0.1 192.169.0.3
25

I tried again and I can now sort of get out onto the broadband internet
whilst connected on dial-up. I say sort of, because I can connect to our SQL
Server instance if I use the explicit IP address, but if I use the alias it
doesn't work. I think that is what was throwing me.

Any idea why the IP would work but not the alias? I have checked the alias
and it is correct. It also works when not on dial-up.

Re: Connect to Multiple Networks (Simultaneously) From Same Comput

Re: Connect to Multiple Networks (Simultaneously) From Same Comput

To rephrase a biblical quote:
"No PC can serve two DHCP servers, for either he will obey the one and
despise the other..."

One of the things a DHCP server gives you (as well as an IP address) is a
DNS server IP address.
This is where your PC asks 'what is the numeric IP address of
www.arsenal.com' so that it can connect you to get updates on the best
football team in North London.

When you are not connected to the secure dial-up, you are getting the
address of a DNS server that works (it knows all about your LAN, and forwards
names it doesn't recognise to the authoritative server for .com, .org, .fr,
or whatever.

When you connect to the secure network, I bet their DHCP server (or their
login script) gives you a DNS server which is not connected to the internet,
so that desktops in the secure network can't browse the web - understandable
as it is a big security hole.

So I guess the operators of that network don't want you to be browsing
through your wireless card while you are connected to them. Ask them for
confirmation of this - or just back off if to do so might light the career
dissipation LED on your desktop!

Nice and clear. Thanks Newell.

I imagined it would have been www.thearsenal.com, but what do I know.

Re: Connect to Multiple Networks (Simultaneously) From Same Comput

We get about one PC infected per year by allowing our 30 employees unfettered
access to the internet.

display sub-assemblies. And an acceptable work load for me!

I would have preferred www.themightyarsenal.com, but they went for the
extreme vanilla version I quoted.
