3. Enter “traceroute 1.1.1.1” and confirm with the enter key. Because this IP
address is invalid on the Internet, the command output will stop when the first
Internet border router is reached. Copy the IP address shown in the last line for
the next step, for example “151.1.1.1”.
4. Enter “ping 151.1.1.1” and confirm with the enter key. Four ping responses
should appear. If this does not happen, check the standard gateway Internet
connection.
5. Enter “nslookup www.aastra-detewe.de” and confirm with the Enter key. The
current IP address of the Aastra Detewe server should appear. If not, correct the
DNS settings for the LAN connection.
6. Enter “start http://www.aastra-detewe.de” and confirm with the Enter key. The
corresponding Web site should be displayed. If not, correct the proxy settings
for the Web browser installed.
In many cases the Internet access router translates an IP address that is valid exter-
nally into multiple locally used IP addresses. This “Network Address Translation”
(NAT) facilitates the use of one Internet connection for multiple computers with
just one valid IP address in one LAN. Many inexpensive or older Internet access
routers use what is referred to as “symmetrical NAT”. This NAT variant is frequently
unsuitable for usage with SIP lines. This is why you should use Internet access
routers that offer the “Full Cone NAT” function or alternatively that function as
transparent SIP/RTP proxy. These kinds of products usually also offer VoIP call pri-
orization (QoS) and configuration of VPN connections.
Note: Q.SIG-IP cannot be operated via a NAT connection.
You will have to configure a VPN connection for a Q.SIG-IP
connection.
3.6.6 Selecting LAN Connection
The Windows operating system can manage multiple IP-capable network inter-
faces. Any additionally installed Ethernet adapters, Bluetooth devices, modem
devices or virtual Ethernet adapters will appear as additional LAN connection in
the Windows network environment. Furthermore, you can configure additional IP
addresses for LAN connections with fixed IP address (“IP aliases”).
The installation program of the Aastra 800 communications system checks during
installation whether there are multiple Ethernet adapters installed and displays a
