Hello all,

I have a PIX 501.  I have multiple users in the field connecting to the 501 via the Cisco VPN Client 4.x.  Any one of them can connect to the VPN and everything is fine, until a second person connects.  Then, the first connection gets cut off.  I have researched the problem and the popular answer is adding:

isakmp nat-traversal 20

to the configuration file in the PIX.  I inherited this network and I am not familiar with the PIX at all.  How do I add this line to the config?

Thank you!

Simple.
Connect to the PIX. Either telnet to it, or connect directly to the console port using Hyperterminal.
pixfirewall>enable
Password: <enter the password>
pixfirewall#config term
pixfirewall(config)#isakmp nat-traversal 20
pixfirewall(config)#exit
pixfirewall#write mem

Or connect to the PIX using the WEB GUI https://<ip address of pix>
Tools | Command line
 isakmp nat-traversal 20
