Examples of V85 Port-Forwarding Configuration

The V85 port forwarding support feature will enable it to traverse any type of NAT/Firewall if you conﬁgure it properly. There are two conditions for use of the V85 port forwarding support.

1)Your broadband Internet service needs to have a ﬁxed public IP address

2)In addition to conﬁguring the V85, you also need to conﬁgure your broadband router to forward a range of ports on its Internet interface to the V85 IP address.

You need to assign a ﬁxed LAN IP to the V85 before conﬁguring your router. See the Further Network Conﬁguration Options, Static IP Method section in Chapter 4 for details. In the below example, the V85 uses a static LAN IP address 192.168.1.144

Most routers support port forwarding, please refer to your router user guide for its conﬁguration. The following screen shows an example of the NetComm NB620W port forwarding conﬁguration. You will need to conﬁgue this to operate with the V85’s port forwarding feature.

Figure D-3

In the above example, the user deﬁned two new virtual server entries, which are identiﬁed by UDP “5999” port with self-deﬁned name “SIPsignalling” and UDP ports “20000 to 20006” with self- deﬁned name “RTPrange”. All Internet trafﬁc that received on these ports will be forward to the user speciﬁed LAN IP address 192.168.1.144 at which the V85 sits.

The V85 port forwarding support setting is shown as below. The user is required to enable the “Port Forwarding Support” option and input the ﬁxed public IP address of the broadband router e.g. 202.44.167.165 in this example. Please note the V85 is also required to be conﬁgured use same port numbers (for both SIP signaling and RTP ports) which are conﬁgured in your broadband router.
