I want to have multiple cisco vpn connections to my network from one external location. One connection is possible but when I start another one on the side it's not possible and the first one stops working.

Is this a setting issue in the Cisco VPN client or on the Pix firewall?

Hope to here soon.

Do you have seperate users for both connections?

If you use the same it will disconnect the first one and connect the second one.

Now I don't have seperate users. I use one group user.

How can I make different user logins? Do I have to do this on the Pix? If so, is it possible the have the windows authentication used in the VPN client, same as with the MS VPN built in RAS?

If you want to setup windows auth with your PIX you need to setup to authenticate with a windows server using RADUIS.

Are you using a PIX501? What software version? i am unsure if it can handle multible users? Is it possible for you to test from 2 different locations? Just to see if the problem presists?

Simple, centralized multimedia control

Watch and learn to see how ATEN provided an easy and effective way for three jointly-owned pubs to control the 60 televisions located across their three venues utilizing the ATEN Control System, Modular Matrix Switch and HDBaseT extenders.

What do you mean by the "one external location" ? In general I dont remember PIX having problems with multiple connecitons of the same user from different locations..

If your simply using group authentication then it should work fine? (thats group authentication with no AAA) so no usernams and passwords in the equation at all!
how many addresses are in your VPN DHCP Pool.

Also are multiple clients coming at you from the same network? if so the problem might be with a firewall at the OTHER end?

Yes, the problem sounds like something is stopping IPsec connections. Please check and see if there is a firewall at the other end filtering IPsec traffic.
Cheers!

It means I got a C on the grade, thus instead of giving me the maximum amount of points I only got 1/6 of them :-(

BTW - the C was picked by the admin by default because nothing was entered by the author - it isn't necessarily a reflection of the quality of my answer - just a standard deal if nothing is entered by the author.
