Hi Guys,

I am not sure it’s just for me but when I click on Listen Now it takes this to episode #27 (IOS Embedded Event Manager (EEM)).

Please let me know if I am doing something wrong.

That was my error, I fixed the link.

Ohh Finesse.... ....

Still, Pix 6.3 without the packet tracer tool or Asymetric Nat logs or RPF tools to check at the NAT configuration is really complicated.

Ohh not to mention the static NATs which actually remained there until you literally do a clear xlate.

Althou I have to say, great Box... it did/does everything you need it to.



I have nightmare about the CLI in Os 4.x on PIX classic. Great boxes still working all these years later.

We still have an HA pair of 535s running our outside Internet edge.


Hey Guys,

Great series, thoroughly enjoying listening to these on the daily commute.

Whens the next podcast of security goodness due out?

     Thanks for writing in! I just submitted our next episode for posting, hopefully it will be up soon (within a week). Then we have another episode ready to go which I'll get into the system in early September.

Any specific topics you'd like us to cover?




Hey Jay,

The one that springs to mind is the CCIE Sec transition from v3 to v4 and the inclusion of ISE, Ironport and a few others.

Also I'd like to hear your take on the ASA-CX series.

I just started listening to your podcasts!  Especially love this one.  I've managed PIXs since having one of the original NTI PIX's starting in 1995, just before Cisco bought them.  Here is a photo of the table of contents of the Command Reference for version 2.6.  I have the book still.  Also have a letter from NTI informing us of the purchase by Cisco.  We are down to just one PIX left on our network, after moving to FWSMs and ASAs.  Thanks! - Bill

Very cool!  Thanks for the pic.

Unfortunately for us, the PIX soon will be history, with End of Support rapidly approaching for the last supported appliances (July 2013).  It will be a sad day to say the least.

We (in the TAC) were talking the other day about what is the longest uptime we have seen on a customer device.  Wouldn't you know we saw a customer's PIX with an uptime of 9 years 26 days !

Yep, we're going to miss them...
