Many firewalls running nat don't like IPSEC as well. IPSEC generally requires that the source and
dest port be 500 however many nat firewalls which are not IPSEC aware will chance the source port to
be above 1024 which can cause a problem for the IPSEC connection.

Also note that some NAT firewalls don't deal with PPTP very well.  E.x.
Checkpoint, PIX, etc.  This is where using IPSEC is a better method, as
the IPSEC clients can work the packets and return packets so you get data
back from the PPTP server.  Also keep in mind that if the local network
you are connecting to the VPN from is using the same network range/subnet
as your LAN network (behind the m0n0wall) it won't route.
