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.
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.
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.
Thanks for the advice.
