RE: 2 different VPNs on different PCs going thru same router allowed? (was RE: DSL reliability)

Dan:
I do this all the time.  When I am at home I sometimes connect to as
many a 3-4 different networks via VPN.  I do not think this is a problem
with the router.  For the record I use a Linksys DSL/Cable router.  The
problem is in how you configure your VPN connection.  I use Win2000 on
my PC, so I am not sure if the same functionality is available in any
other version of Windows.  But the problem is, once you start a VPN
connection, all your traffic is routed to the VPN adapter.  There is a
way to fix this.  (Have you ever connected via VPN and found that you
can not send mail to your ISPs SMTP server?  It is because your PC is
trying to connect over the VPN adapter, and not your DSL connection).
In W2000 do this.  Open up the properties of the VPN connection in Dial
up Networking.  Click on the networking TAB, highlight TCP/IP and click
on properties, click on advanced, under the GENERAL tab, be sure the
"use default gateway on remote network" in NOT checked.  This will allow
all traffic that is not destined to the VPN network to be routed over
your original PPP connection (dial up or DSL).  You should be able to
connect to more than one network via VPN.

This thread got me thinking.  I'm close to putting a broadband router on
the "front" of my cable connection and hooking up two (or more) PCs to
it so my kids and I can surf at the same time.  I use a VPN connection
to connect to our AS/400 (actually network) at work.  Sometimes I'd like
to VPN to one of our clients at the same time, but I'm not able to get
two VPN sessions running concurrently.  If everything goes through the
router to get to the internet, can I use the other PC to VPN to the
client while my PC VPN's to my company's network?

Using a similar setup has worked very well for me.   That is until my
son cranked up the napster (or was it FTP?) and my daughter started her
chat sessions!  Then the dropping of sessions began.

Found that if there is a bunch of Internet traffic on either side of the
VPN connection that drop-out/interruptions will occur.  Packet shaping
and Parental Grumbling has helped with this issue!
