RE: NAT rules for VPN only allowing one user?

I took a quick look at the user guide but didn't see a lot
of
information on the VPN.  Does Linksys have a forum or
mailing list that
addresses this?  Maybe someone there's run into a similar
problem.

So this is a limitation of the Linksys router, correct? 
What are the
real requirements for user connections? 

Linksys has the BEFVP41, that supports up to 50 VPN
connections.  Maybe
an upgrade to this box is in order.  It's on Amazon for $99.
 What
router are you using right now?  If it's a WRT54 series
wireless router,
there might even be an image you can flash it with to do
what you want
right now.

Hey,

This sounds like a problem on the VPN gateway device, you
should remove
the rule:

"/sbin/iptables -t nat -A POSTROUTING -o eth1
        -d $LINKSYS_VPN_IP -p tcp --dport 1723
        -j SNAT --to-source $ETH1_IP"

And resolve that issue, what is most likely currently
happening. Your
VPN router is only setup for or only supports 1 VPN
connection per IP
address. So a second connection would over write the first
one.
