Watch hostname of remote VPN Gateways? Yes / No
If the address of the remote VPN Gateway has been given to
the SINAUT MD740-1 as a hostname (see VPN
page 37), and if this Domain Name has been issued by a
DynDNS service, then the SINAUT MD740-1 can check
regularly whether any changes have been made to the DynDNS
concerned. If so, the VPN connection is established to the new
IP address.

To establish VPN connections at least the IP address of one of the
partners must be known so that they can make contact with each
other. This condition is not fulfilled if both participants are assigned
their IP addresses dynamically by their Internet service providers.
In this case, however, a DynDNS service such as DynDNS.org or
DNS4BIZ.com can help. With a DynDNS service the currently valid
IP address is registered under a fixed name. See also IP address
of the remote site, page 9
Once you are registered with a DynDNS service supported by the
SINAUT MD740-1 you can make the corresponding entries in this
dialogue box.
Register this TAINY at a DynDNS Service? Yes / No
Select Yes if you are registered with a DynDNS provider and
the SINAUT MD740-1 is to use the service. Then the
SINAUT MD740-1 reports the current IP address assigned to its
own Internet connection by the Internet service provider to the
DynDNS service.
