Hi Guys, <br />
<br />
I would like some advice on which Cisco Equipment to use to create a good and fast and potentially redundant VPN implementation. The connection will be used to connect one LAN to another LAN by aggregating DSL lines on one LAN to come into a E1 connection on the other LAN.<br />
<br />
The idea is to have good equipment and low latency caused by any network equipment and be secure to a normal standard like 3 DES.<br />
<br />
I was thinking of having a PIX on the primary site and a VPN concentrator. Whats the advantage of having both. Would I then need both on the remote side too or could I get away with just a Pix on the remote side. I.E is there such a difference in using PIX alone, or with VPN accellerator cards, or with Concentrators. Also how do you aggregate DSL connections to use over this. <br />
<br />
Thanks for the advice.

VPN Setup Advice

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
