I am currently running a 2821 to terminate vpn links from all our branch offices over a WAN. I need to add a second interface in order to facilitate a move to a different WAN provider. seeing as the 2800 models are EOL I was looking for an upgrade. My local retailer wants to sell me the following:
CISCO3925E-SEC/K9 IS Router 3925E security bundle
SEC license pack
HWIC-2T 2 port serial WAN card
MEM-3900-1GU2GB Upgrade to 2GB 1
PWR-3900-AC/2 AC power supply secondary 1
now my question is why can't i use the 2900 models in order to save some money?
All I need is a router that will accept 2 different incoming WANs and the ability to create vpn tunnels over them.. So i defer to the experts to see if you guys can enlighten me a little and hopefully save me some money.
Thanks
P.S if you coudl include part # that woudl be great.

Sory, misunderstood the ethernet thing.
You will be fine with a secury bundle router then, and nothing else. You wanted to know about the high perfomance security license, here it is:
The HSEC-K9 license removes the curtailment enforced by the U.S. government export restrictions on the encrypted tunnel count and encrypted throughput. HSEC-K9 is available only on the Cisco 2921, Cisco 2951, Cisco 3925, Cisco 3945, Cisco 3925E, and Cisco 3945E. With the HSEC-K9 license, the ISR G2 router can go over the curtailment limit of 225 tunnels maximum for IP Security (IPsec) and encrypted throughput of 85-Mbps unidirectional traffic in or out of the ISR G2 router, with a bidirectional total of 170 Mbps.

As i was thinking, this will do:
CISCO2921-SEC/K9 IS Router 2921 bundle
SEC license pack <-- as i don't need faster that 170Mbps bi-directional and have less that 255 tunnels
But i still need the extra port for the second Temp WAN (copper ethernet)
and from the 2900 product description it seems it comes with 3?
So i would not need to purchase an extra one?
But if i did this one would do?
Cisco Gigabit Ethernet EHWIC-1GE-SFP-CU

Router has three interfaces, after that you can use a switch. So as mentioned before already, you do not need anything else.
Thank you for the nice rating and good luck!

So will this support what i need?
Don't know as it's not totally clear what you are doing now and what you might need.
Like Paolo, I think it very doubtful you'll need the memory upgrade.
You're rep probably now mentioned the 2921 as that's the logical successor for the 2821. However, newer ISRs are faster then earlier models, so for the same performance, a "smaller" ISR might be fine.
As one of your later postings mentions Ethernet handoffs, how much aggregate traffic do you need to deal with? The document Paolo provided will help you to select the "right" size router. BTW, the recommendations pretty much assume almost every feature with traffic running at 100% of the noted bandwidth; i.e. worst case. If you size for "average" bandwidth loading, you might find you can size down a model or two from "maximum" bandwidth loading. How safe it's doing this depends on how much average diverges from peak and whether slow down during peak is acceptable.
