IPsec with racoon

[rduvall at onlinehighways.net]

Is the external IP address of your VPN device an internet routable IP address?  
I know that if you are on an ADSL without static IP (like Qwest or MSN adsl) the 
IP address that is automatically assigned via DHCP by the DSL modem is private 
IP space, and therefore your VPN will not work.  I resorted to getting an 
Alcatel Speedtouch USB modem and plugging it into a FreeBSD box for my Qwest MSN 
and set my VPN to go between the 2 FreeBSD boxes.  This gave my firewall/gateway 
a real IP address.  Granted, it is dynamic and I have to change my vpn every 
time my IP address get's re-negotiated, but at least it works.  I am trying to 
figure out a way to dynamicly change the VPN config on both ends when ppp comes 
up so I don't have to do it manually.

Sincerely,

Rick Duvall
