VPN with FreeBSD using some form of encryption

[Baldur Gislason]

I have a home network with FreeBSD machines and a laptop running FreeBSD.
The laptop connects to various networks but I'd like to access my home 
machines from the laptop, the home machines are behind a freebsd nat 
firewall.
I've been using mpd for quite a while, doing a PPTP link from my laptop to 
home but it doesn't offer any useful encryption, and the encryption it claims 
to offer doesn't seem to work.
Hence, limiting what I can do over the link without fear of being sniffed.
I'd like being able to dial in from anywhere, yet have an encrypted link. What 
are my options?
I've read about the IPSEC tunneling support but it seems to me that it's 
limited to static tunnels.
