The Lan Screen - ZyXEL Communications X6004 User Manual

• 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.
