I have several Cisco 3002 VPN Clients connecting to a Cisco 3000 Concentrator. &nbsp;The firmware needs to be upgraded. &nbsp;This can be done via the Concentrator as a push out to each vpn client, but my sites are too far apart and since it requires intervention on the client side, ths is not a very good idea. &nbsp;So I want to go to each site and upgrade each one. &nbsp;I am not finding any instructions on how this can be done. &nbsp;Any help would be most appreciated. &nbsp;Thank you in advance.

How to upgrade a Cisco VPN 3002 client manually?

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
