Modem Router with FQDN to Gateway B

This section is a case study on how to configure a VPN tunnel from your modem router to a
gateway using a fully qualified domain name (FQDN) to resolve the public address of one or
both routers. This case study follows the VPN Consortium interoperability profile guidelines
(found at http://www.vpnc.org/InteropProfiles/Interop-01.html).

Configuration Profile

The configuration in this section follows the addressing and configuration mechanics defined
by the VPN Consortium. Gather the necessary information before you begin configuration.
Verify that the firmware is up to date, and that you have all the addresses and parameters to
be set on both sides. Check that there are no firewall restrictions.
