Therefore, communication, software, and networking, which are based on layer 2 and broadcast packets , such as NetBIOS used in Windows networking , may not be fully supported or work exactly as they would on a real LAN. A VPN connection may not be as robust as a direct connection to a network. If either fails, the connection fails. From Wikipedia, the free encyclopedia.

Our example setup is between two branches of a small company, these are Site 1 and Site 2. Site 1 is configured with an internal network of The goal is to securely connect both LAN networks and allow full communication between them, without any restrictions.

This means that if we have five different remote sites and configured five different ISAKMP Phase 1 policies one for each remote router , when our router tries to negotiate a VPN tunnel with each site it will send all five policies and use the first match that is accepted by both ends.

Next we are going to define a pre shared key for authentication with our peer R2 router by using the following command:. Next step is to create an access-list and define the traffic we would like the router to pass through the VPN tunnel.

In this example, it would be traffic from one network to the other, Access-lists that define VPN traffic are sometimes called crypto access-list or interesting traffic access-list.

Next step is to create the transform set used to protect our data. The ipsec-isakmp tag tells the router that this crypto map is an IPsec crypto map.

Although there is only one peer declared in this crypto map 1. The final step is to apply the crypto map to the outgoing interface of the router.

If the Internet router or any router between the firewall and the VPN server is providing NAT, it will probably break the VPN tunnel and cause your connection to fail. Site-to-Site IPSec VPN Tunnels are used to allow the secure transmission of data, voice and video between two sites (e.g offices or branches). The VPN tunnel is created over the Internet public network and encrypted using a number of advanced encryption algorithms to provide confidentiality of the /5(). Difference Between VPN and Firewall is that the VPN is the secure connection created over the Internet between the user’s computer and the company’s network is which is known as VPN tunnel. While a firewall is hardware and/or software that protects a network’s resources from intrusion by users on another network such as the Internet.
