cisco site to site vpn and remote access

A site-to-site VPN

is a permanent connection designed to function as an encrypted link between offices (i.e., “sites”). This is typically set up as an IPsec network connection between networking equipment. A remote access VPN is a temporary connection between users and headquarters, typically used for access to data center applications.

How does IPSec work?

In IPSec tunnel mode, the entire original IP datagram is encrypted, and it becomes the payload in a new IP packet. This mode allows a network device, such as a router, to act as an IPSec proxy. That is, the router performs encryption on behalf of the hosts. The source router encrypts packets and forwards them along the IPSec tunnel. The destination router decrypts the original IP datagram and forwards it on to the destination system. Tunnel mode protects against traffic analysis; with tunnel mode, an attacker can only determine the tunnel endpoints and not the true source and destination of the packets passing through the tunnel, even if they are the same as the tunnel endpoints.

What is IPSEC security?

IPSec is a framework of open standards, developed by the Internet Engineering Task Force (IETF), that provides data confidentiality, data integrity, and data authentication between participating peers. IPSec provides these security services at the IP layer; it uses IKE to handle negotiation of protocols and algorithms based on local policy, and to generate the encryption and authentication keys to be used by IPSec. IPSec can be used to protect one or more data flows between a pair of hosts, between a pair of security Cisco 7200 series routers, or between a security Cisco 7200 series router and a host.

What is the simplest way to connect to the Internet?

The simplest connectivity to the Internet is to use a single device to provide the connectivity and firewall function to the Internet.

This normally leads people into building a network where the corporate network touches the Internet through a network called the DMZ, or demilitarized zone.

Where is NAT configured?

NAT is configured on the router at the border of a stub domain (referred to as the inside network) and a public network such as the Internet (referred to as the outside network ). NAT translates the internal local addresses to globally unique IP addresses before sending packets to the outside network.

What is the encryption key for VPN?

Encryption key is another thing that should be identical on both routers that participate in the VPN tunnel formation. I recommend making it no less than 50 characters so that it contains digits, letters and special characters. For this example, we’ll just use a simple “ 12345 ” key, but that’s not a good idea for a real VPN tunnel.#N#For the main office:#N#R-MAIN (config)##N#crypto isakmp key 0 12345 address 2.2.2.2#N#For the branch office:#N#R-BRANCH (config)##N#crypto isakmp key 0 12345 address 1.1.1.2#N#The configuration example has the values that you should change to your own highlighted in red. The “ 0 ” in the “ crypto isakmp key ” line means that the key is being entered in an unencrypted form. You should not change this to any other value. When you look at the running configuration, in certain cases the crypto key gets encrypted and displayed in a scrambled format. This is indicated by the number “ 7 ” after the “crypto isakmp key”:#N#R-MAIN#sh run#N#/...output cut.../#N#crypto isakmp key 7 ^bn UjbsdfgsujGsdf address 1.1.1.2#N#/...output cut.../#N#This does not mean that the key itself has changed, it means that it is displayed (!) in an encrypted format.#N#Note that on each router we are specifying the external IP address of the remote location (i.e. we are saying use this key to communicate with this remote mate’s address)
