Good book to learn proper XP VPN implementation?

Archived from groups: comp.dcom.vpn (More info?)

I have successfully setup VPNs using Pix 506e firewall and the Cisco VPN
client software. I didn't realize how spoiled I was using the Cisco
software, it has a "wizard" style configuration that let me have working
VPNs setup in minutes, literally.

Lately in my spare time I have been trying to setup a VPN using XPs built in
VPN support. I am trying to get IPsec to work but I am having the worst
time. With NAT-T, hardware and software firewall configuration, vpn
passthrough, anti-virus software, and authentication/encryption settings I
am getting to the point where I don't know WHAT the problem is.

I would like to buy a book that focuses on VPN implementation, and
preferably it would also be specific to Windows XP SP2. Any tips?

Thanks,
