PIX 3DES Licenses

We are getting some mixed signals from our resellers concerning PIX 3DES upgrades for a 515-UR & 515-FA set-up. Basically we were informed that we only needed to purchase a 3DES upgrade for the main PIX (515UR), while the backup could continue to have DES.

Subsequently we have found that when the fail-over unit comes online, 3DES support disapears.

So now it looks like we need to purchase a upgrade license for the FA PIX. The question then becomes "What is the part number to purchase this?"

From the parts list I have it appears that:

PIX-VPN-3DES= 168-bit 3DES VPN feature license for PIX Firewall

Is what we need to buy.

Does this make sense?

Re: PIX 3DES Licenses need to buy PIX-VPN-3DES= to get 3DES VPN feature license key for PIX Firewall.

Ideally you need to send email to with the serail number of PIX, version of software on pix, and company information and request to have a 3DES license key for PIX. They will be able to assis you for that.
