I need help setting up an intranet VPN for our company. We have two 1721 Routers that we've recently acquired. The IOS version is 12.3(1a). I've defaulted both units and removed all passwords. Could someone please provide me with a detailed step by step procedure on setting up a VPN to connect two sites together? I'm in the process of taking my CCNA but I'm a little overwelmed with this project. Thank you.
Before you get to far along do you have an IOS that will support IPSec. If you're not sure please post the file name of the IOS currently running on the Router.
