2800 Interface Question


I have a Cisco 2811 router. It is currently being used for a 10mb encrypted, ELAN WAN connection to a remote site via a built-in FE port. It is connected to our core via the other built-in FE port. The ports used are Fasterthernet 0/0 and 0/1. From the output I provided, if I were to install another 2-port fastethernet card in one of the free slots, is there a way to tell if I will be able to create another encrypted tunnel using that new card? I'm concerned because of the 3rd line of output below. - NAME: "Virtual Private Network (VPN) Module on Slot 0", DESCR: "Encryption AIM Element"

I'm wondering if I am only allowed to create VPNs on Slot 0.

If that is true, could I create the Encrypted interfaces that connect to the sites on Slot 0, and use the LAN ports on the new slot?

Thanks, Pat.

You should be able to create another encrypted tunnel if you install additional FastEthernet card in the router. The AIM-VPN/SSL-2 in slot 0 is a hardware assist for encryption processing which relieves the CPU from having to do much of the crypto processing. The slot 0 that it is in is not the same as the slot for the FastEthernet Cards.

Thanks for the response. I'm not sure what I should order to a slot on the 2811. Is there a module that is specific for that router or will any cisco, 2 port, fastethernet module do?

Thanks, Pat.
