I've got the VPN working on my XP laptop, but when I went to install the client on other laptops in the office, I ran into trouble. The other machines have Vista and version 4.6 of the VPN client isn't compatible.
I went to Cisco's website to download version 5.x and was told that I couldn't download it without an active service contract. This is a new router and I should be able to get a client for it. What do I have to do to get a usable client?
