I have an Enhanced Easy VPN server running on a 2801 router at my corporate office. &nbsp;I am using 851W routers in the field to connect with Easy VPN remote. &nbsp;This is working great from three locations with cable modems, but when i place an 851W at any of my Bellsouth DSL sites the VPN tunnel establishes connection and stays up for 2-4 minutes and then I lose connectivity. &nbsp;The VPN light is on on the router at the branch office and it shows as up from the SDM. &nbsp;And then every hour on the hour for 1 minute the tunnel comes up. &nbsp;If i ping -t the ip of the remote router from the corporate office with it is up for that 1 minute it will stay up as long as i keep pinging it. &nbsp;It was up for 12 hours last night and when i ended the ping it was down in just a few minutes. &nbsp; I am running 12.4 on the 851s. &nbsp; The funny thing is that i can take this same router with the same config and put it at a cable modem site and the tunnel never fails.<br />

Enhanced Easy VPN tunnel establishes and then drops from DSL.

The term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access. Broadband includes several high-speed transmission technologies such as digital subscriber line (DSL), cable, fiber optics, wireless (for which there is a separate topic), satellite and broadband over powerlines (BPL).

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.

Internet Protocol Security (IPsec) is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite.
