What is the minimum memory required to run Zone based firewall on 2651XM?

I was watching the CBT nuggets CCNA security!

and saw Jeromy using 2621xm router to configure zone based firewall!

I just bought one 2651xm from eBay and it does not seem to support that feature.

It has 96MB of memory and 32MB flash.

Do I need to upgrade it to 128MB of memory? or do I need to upgrade the flash
plus memory to 256MB to get that feature?

also what is the minimum IOS that support that feature?

Thank you in advance!

    You need 32MB flash & 128MB DRAM for ZBF

    Zone based IOS firewalls showed up in 12.4(6)T -- but some additional feature/fixes showed up in 12.4(9)T and 12.4(11)T so you want one of those (or greater).

    You also want the Advance Security Feature set or greater (Advanced IP Services or Advanced Enterprise Services).

    The memory required will be determined by the feature set (and version) you run -- so

    link to look that up. Just remember that you may be able to get by with less memory in a lab environment if they haven't hard coded the memory required into the IOS file -- so you won't know (in a lab environment) until you try.

    You can find a PDF for the IOS Packaging (which describes the IOS Feature Sets) on the Cisco Partner Central Portable Product Sheets web page:
    Portable Product Sheets - Partner Central

    There will also be other useful PDFs there: Router Memory, Router Performance, Switch Performance, Modules Cross Reference, etc
