I HAVE A REMOTE SITE CONNECTING THROUGH A CISCO 1841 ROUTER VIA DMVPN TUNNEL0 USING THE TUNNEL SOURCE AS THE FASTETHERNET CONNECTION WHICH IS AN ADSL CONNECTION - I WANT TO CREATE ANOTHER TUNNEL INTERFACE ON THE ROUTER - TUNNEL1 (FOR EXAMPLE) AND ENABLE THE CELLULAR 0/0/0 CONNECTION TO BE THE SOURCE FOR TUNNEL0.

At present the default route is ip nat inside source list acl_nat interface FastEthernet0/0 overload and <br />

CHANGE A TUNNEL CONNECTION TO USE A CELLULAR CONNECTION

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

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.

Internet Protocol Security

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries, organized in abstraction layers, traditionally called "Link," "Internet," "Transport" and "Application”. Its routing function enables internetworking, and essentially establishes the Internet. IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information.
