SINAUT MD740-1
Address of the remote site's VPN gateway
•
This denotes the address of the gateway to the private
network in which the remote communication partner is
located - see illustration below.
GPRS

Remote VPN
gateway address

If the SINAUT MD740-1 is to initiate and establish the
connection actively with the remote site, then enter the
remote site's IP address here. Instead of an IP address you
can also enter a hostname (i.e. domain name in URL format
in the form www.xyz.de).
If the VPN gateway of the remote site does not have a fixed
and known address, a fixed and known address can
nevertheless be simulated by using the DynDNS service. See
IP address of the remote site, page 9.
•
If the SINAUT MD740-1 is to be ready to accept the
connection actively initiated and established by a remote site
with any IP address to the local SINAUT MD740-1, then
enter: %any
Then a remote site which is assigned its own IP address (by
the Internet service provider) dynamically, i.e. has a changing
IP address, can "call" the local SINAUT MD740-1.
If only one particular remote site with a fixed IP address
establishes the connection, you can enter this address to be
on the safe side.
!
In order for the SINAUT MD740-1 to accept a connection
actively initiated and established by a remote site, the
SINAUT MD740-1 requires a fixed IP address from the
provider or by using a DynDNS service.
!
In many GSM/GPRS networks it is not possible to set up
connections initiated from a remote site to the GPRS
device (SINAUT MD740-1).
