Cisco PIX 515e Allowing Only One Client VPN at a time.

I have clients VPNing into my PIX 515e just fine, as long as only one client connects at once.  The second client cannot connect until the first disconnects.

Any top 5 ideas why this might be the case?

    What version of the IOS are you running?
    Can you post a sanitised configuration?

    you mean from the same public IP (meaning multiple clients that are nat'd) which just means add the
    isakmp nat-traversal 20
    command, or do you mean at all regardless of the public IP the users are connecting with.

    but agree with keith, please post your PIXOS version and a sanitized config so we can look it over.

    Hi Cyclops3590,

    I do mean regardless of the public IP they are connecting from; the users are all at different homes/hotels.

    I will post the Cisco config shortly.

    It was a problem with the IP pool assigned to VPN:

    Result of firewall command: "sh ip local pool vpnpool"
    Pool            Begin           End             Mask             Free    In use
    vpnpool   Not configured      1         0
