Hello all,<br />
<br />
I have a PIX 501. &nbsp;I have multiple users in the field connecting to the 501 via the Cisco VPN Client 4.x. &nbsp;Any one of them can connect to the VPN and everything is fine, until a second person connects. &nbsp;Then, the first connection gets cut off. &nbsp;I have researched the problem and the popular answer is adding:<br />
<br />
isakmp nat-traversal 20<br />
<br />
to the configuration file in the PIX. &nbsp;I inherited this network and I am not familiar with the PIX at all. &nbsp;How do I add this line to the config?<br />
<br />
Thank you!

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:

Thank you!

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.
