Scott, Your router does Network Address Translation - NAT. It has one real, routable, on-the-internet IP address. Your two computers, when connecting to anything on the internet, appear to have that one-real-routable IP address. Your VPN server/firewall/device sees the first connection from Computer A using IP address X - the one-real-routable IP address. The session is set up and humming along. When Computer B tries to set up a session, it also shows up as IP address X. The VPN server, depending on that address to be unique, drops the Computer A session and sets up a new one. As far as I can tell, you need a different kind of solution. Some possibilities, in order of increasing complexity: 1. Set up the VPN connection from the Netopia router (if it supports such a function). Then your two machines can talk over the same tunnel to your VPN server. 2. Take the Netopia router out of the picture, buy a second IP address from your ISP, secure your two computers with host-based firewalls, and away you go. 3. Deploy a second VPN device at the network to which you're connecting (conceivably, you could just add an IP address to the VPN server, who knows). Connect one client to each VPN device or address using your current home network setup. 4. Deploy a different VPN technology which can accept multiple sessions from the same remote IP address. Good luck. -David -----Original Message----- From: firewall-wizards-admin () honor icsalabs com [mailto:firewall-wizards-admin () honor icsalabs com] On Behalf Of DeMoss, Scott Sent: October 23, 2003 4:54 PM To: firewall-wizards () nfr com Subject: [fw-wiz] (no subject) I happened apon your e-mail address while searching for an answer to a VPN problem I am having... So, I am sending a question in hopes that you are the Genie in the bottle that I have been looking for. I run my VPN through a Cisco Client to my main office. It worked fine going through enternet 300 and then through a Netopia Cayman 3546 ADSL router. I put the router in place to access the VPN through two computers. I get the internet with both computers but I get kicked off the VPN at one computer when I try to log on at the other? But it works fine while I am on. So, can I not log on from two locations, even though I have internet from both locations? Or is there something else I need to do? I was told that the router was the answer..... so far it is not. I am on DSL, if it makes a difference. Any reply would be great..... even "get lost" :) But the cure would be great? Thanks, Scott Scott A.
