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?

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.

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

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         192.168.221.0   192.168.221.0   Not configured      1         0
Available Addresses:
192.168.221.0

Thanks.
