I've been tasked with setting up a VPN from a static IP on an 1841 router to a dynamic ADSL connection on an 1801 router. I need to setup a site to site VPN as well as make the 1841 accessible for remote users from client VPNs. This will be a first for me setting up VPNs and I'm looking for some examples and help up front so I know what I'm getting into. Any example scripts and warnings of trouble spots I might run into is helpful.
