Dynamic VPN Rule
A dynamic IPSec VPN rule does not specify the remote IPSec router’s IP address or domain name. This allows a remote IPSec router with a dynamic IP address to initiate a VPN tunnel to the local IPSec router (the one upon which you configured the dynamic IPSec VPN rule). Only the remote IPSec router can initiate a dynamic VPN tunnel.
