I am trying to allow three people to access a Cisco PIX firewall via Cisco VPN client 4.02. They are connected to the internet via Charter Cable High Speed Internet and a Motorolla modem with a Dlink DI604 router. One person at a time can connect fine. Once the second user tries to connect the currently logged in user will be bumped off with a 433 error. I am trying to figure out if this is a limitation of the client or either of the routers or the ISP???? Any info would be greatly helpful. Thanks.
No one has been able to assist me with this problem and Cisco wants $420.00 to maybe or maybe not solve the problem.

You cannot do this, I had the same problem with a Watchguard SOHO firewall, you can only connect one client at a time. The way to fix this would be to buy a second vpn router on your side, and make a permanent tunnel between the 2 locations. After this, you would be able to have unlimited connection from 1 site to another.
Ok, I am getting conflicting reports from the two feedback recieved. Do you think I can use a different router to allow this??? I have tried a different VPN router (DI804HV). Still had same problem. The problem is that I am connecting to another companies router who does not want this company to create a tunnel. Would rather have them use the client instead of connecting all users on that comapnies network. Any insight???? Thanks for the comments.
This D-Link product specifically states that it supports multiple VPN pasthru sessions

I don't understand what you mean by your last comment. The other comany wants you to setup lots of client to LAN VPN sessions instead of using LAN-LAN VPN?
grblades,
Yes as messed up as this sounds they would like to have only the three clients on the remote network that need access to their software. They do not want the other 7 in the office to see their network. I am going to give the DI624 a try and see. Will let you know on Monday. Again, thanks so much for your help...
Hi,
I can assure you that this works fine, what you need to look at is the Pix does is support client vpn connection on port TCP 10000 (or any random TCP port) I think the latest version of software may support this. The main problem is usnig UDP behing a NAT service and you have one client connected, when you try to connect the second client the trafffic cannot determine where to go as it already has a connection going through and therefore the second client will not get the response back. I have installed this solution several times over the only difference is that the VPN at the head end is a concentrator which supports client connections on TCP as well as UDP.
No if the Pix will support clients connections on TCP all you will have to do is configure your client to use TCP 10000 instead of udp 500. I have to admit having looked on the Cisco web site and I cannot find any details of the Pix supporting this. I have been told by another engineer that the new software on the Pix would support this. If I find anymore detail I will post hem on here.

Hi obtech,
It is a limitation of the D-Link router. Most routers only support a single IPSEC passthru connection. Some of the newer D-Link VPN router support multiple sessions.
