CHAPTER 6
Network Deployment
This chapter shows you how to deploy the X6004 on your network.
6.1 Network Deployment Overview
The following diagram shows a sample network deployment of the X6004. The WAN port is
connected to a DMZ interface on the default gateway router. The X6004 uses the WAN
interface to connect to a SIP server at the ITSP. SIP IP devices use the WAN IP address of the
X6004 to connect to it.
On the LAN, SIP IP phones use the LAN IP address of the X6004 to connect to it.
Figure 74 Network Deployment Overview
When you deploy the X6004, you must consider the following:
• If the X6004 has dynamically assigned IP address from your ISP, then you should
configure DDNS (Dynamic DNS). DDNS maps your dynamic IP address to a static
domain name. This allows the IP devices on the WAN to establish connections with the
X6004.
• If the X6004 is behind a firewall, then you must make sure that you create firewall rules to
let VoIP traffic pass through to the X6004.
• If the X6004 is behind a NAT router, then you must make sure that you configure
forwarding rules for VoIP communication to get to the X6004.
• If the IP phones on your LAN are located in different subnets, then you have to configure
static routes to ensure that the IP phones can connect to the X6004 and vice versa.
