The importance of using tunnels in a VPN environment is based on the fact that IPSec encryption only works on IP unicast frames. Tunneling allows for the encryption and the transportation of multiprotocol traffic across the VPN since the tunneled packets appear to the IP network as an IP unicast frame between the tunnel endpoints. The 3845 like all ISR router does already have an embedded hardware module for IPsec. The AIM is more for SSL based Vn that are something else. Anyway, if you are positive that there is no growth and only the wto LAN have to communicate with encryption, I would configure a traditional IPSEC VPN. I have setup my Cisco 3845 in full tunnel. I’m getting horrible speed. My network line into the house is 100/30 mbps. When I’m testing the speed in AnyConnect from a location with 100/100 mbps line, I get 10/8 mbps. When testing home, exactly the same speed with external IP. With internal IP, I get maybe 3-4 more mbps. I have a 3845 Integrated router.It is located at my corporate office and connects to the Internet ( e0).The branch office has a DS3 connectivity to it for internet acccess ( s0).I want to enable IPSec remote access on this router so that users can use the cisco VPN client to connect to it and access the corporate and branch office resources. A configured router added to a session establishes a VPN tunnel to Cisco dCloud automatically when your session is active. This process is typically transparent and reliable. In situations where you are unsure if the VPN tunnel is established or for additional information when troubleshooting, use the steps on this page. Pre-requisites 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 data transmitted between the two sites. GRE Tunnel IP Source and Destination VRF Membership allows you to configure the source and destination of a tunnel to belong to any virtual private network (VPN) routing/forwarding (VRFs) tables. A VRF table stores routing data for each VPN. The VRF table defines the VPN membership of a customer site attached to the network access server (NAS).
