Road Warrior
A "Road Warrior" is defined as a remote machine whose IP address is unknown at
this time. It may be a sales employee dialing into local ISPs while on the
road or it may be an engineer at home on his cable modem.
When this machine is checked then the secret/profile (whichever is
appropriate) will be valid for any IP address. Obviously this has some
impact on the security of the VPN, so you should try to use static IP addresses
whenever possible.
