one boat, so to speak, by obtaining a Fully Qualified Domain Name (FQDN)
and registering at least one site with a Dynamic DNS service. This service
associate tracks your dynamic IP address to ensure that your router is
reachable even when the address changes.
As illustrated below, Dynamic DNS service ensures that traffic for the FQDN,
MyBusiness.DynDNS.org, is routed to the dynamic IP address.

Free Dynamic DNS accounts are available through many providers.

LAN Setup
The LAN setup pertains to the network that your router connects to inside your
office. It should not be necessary to make any changes in your LAN setup, unless
both sites have the same addressing. The two ends of the tunnel cannot be on the
same subnet. For example, if the LAN IP address of the RV0xx router at Site A is
192.168.15.1, Site B must use a different subnet, such as 192.168.75.1.
