I've got two users trying to hit our VPN concentrator (Cisco 3005) from behind some sort of firewall. I'm not sure yet of the details of the firewall, but I'm trying to find that out.
These two users cannot be connected at the same time.
They're both making PPTP connnections to us with the built-in W2K client. It looks like from the logs, the first one succeeds and the second one gets a "denied -- already established" message. Both users behind the firewall have the same external IP. Is this what's causing the second connection to be denied.
What's the simplest way to allow both these users to connect at the same time?
