Setting up Cisco VPN client on PIX

Posted on 2008-10-03
Last Modified: 2012-05-05
I have a Cisco PIX 515 in place at my office.  I average about 30-40 remote users daily.

Our current VPN connection is the Windows remote access server on a windows 2003 server.  

I would like to enable the vpn client on the PIX.  I have a site-to-site VPN enabled now between one other office.

What is the best/easiest way to enable the vpn client on the PIX and am I limited to the client vpn version for my users?

The PIX 515 should have plenty of power to handle 30-40 users. Just make sure you have a license for that number of users - you can check this by running the sh ver command. This number only applies to simultaneously connected users. Even if you have 500 users total, as long as the number that connect at the same time is the same or fewer than the licensed number you are good.
You can download the latest software for the PIX at the following link. I HIGHLY suggest you upgrade to the newest software before trying this as upgrading enables new features and fixes bugs.
Just make sure you have enough flash/RAM for the new software. I recommend the 8.0.4 version. It is very good.
As far as software goes, you will need to use the Cisco VPN Client. You can reach that from the same link above.
One other thing - when setting up the VPN make sure you use DH group 2  or the Cisco VPN Client won't work.
Cheers! Let me know if you have any questions!

The easiest way is to use the vpn wizard in PDM GUI.
Best is to upgrade the PIX to version 8.0(4), ASDM 6.13 GUI, and then setup the vpn.
You are not limited to the Cisco VPN version, but the latest 5.x client works best with both XP and Vista. The client is free and there is no limit on how many users you can support.

@Pug - there is no user limit on 515 based on license.

@sk_raja_raja - we expect at least some explanation as to why you are posting a link, and what the user can expect to find in that link. Almost every answer to almost every question regarding Cisco product can be found at as long as you know exactly what to search for and have the skills to determine which option is most appropriate for the asker's question.

Lol I guess I forgot to even mention the PDM even though I said to check the DH group 2 option in it. Thanks lrmoore!
My mistake on the PIX 515 license - thinking of the ASAs... funny how Cisco brought back the VPN user limit with the ASAs isn't it? You know they just lloooovvve those license fees.
Agreed with lrmoore on raja's post... wtf?

I currently have the following on my PIX:

Version 6.3(3)
PDM Version 3.0(4)
Flash 16MB

Guess I can't go to 8.0

Can I set this up anyway and does it matter which VPN client I use, or are they all the same?

you can't use 8.0... you need 64 MB for that.
Go ahead and use 7.2(4). It's a huge improvement over 6.x and it only needs 16MB of RAM.

You need a RAM upgrade because you need 64MB RAM to run any version of 7 or 8.x
I bought a 32Mb stick for < $50
PIX515-MEM-32=   is the part number, just google it for a good price

Then you can run anything you want, including the latest 8.0(4)

Otherwise, you can upgrade what you have to 6.3(5) and PDM 3.14 which is still an improvement over what you've got.
Use almost any VPN client 4.x or 5.x

Yes that's right - I meant 64MB RAM and 16MB flash.
