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”.

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.
