USG LITE 60 AX - IPTV Interface

Zyxel_Claudia

The IPTV interface feature in the USG LITE 60 AX is designed to support triple-play services provided by ISPs. These services typically include IPTV, internet access, and VoIP. However, in this implementation, we focus on IPTV and internet access, with VoIP potentially being added in future updates.

Background: Triple-Play Services

Triple-play services utilize different VLANs from the LAN interface:

• VLAN X for IPTV
• VLAN Y for internet access
• VLAN Z for VoIP (future consideration)

For IPTV services in home networks, especially provided by ISPs, the USG LITE can be configured to bridge the WAN with the LAN port to ensure compatibility and smooth operation.

IPTV Scenarios

There are three main scenarios for IPTV configuration:

1. Bridge Mode
   • Scenario: The IPTV subnet is the same as the LAN subnet and the ISP subnet.
   • Configuration:
     • IPTV devices send untagged traffic to the router on port one, which is forwarded directly to the ISP network.
     • LAN clients on ports two to five will connect to the LAN interface and use NAT for internet access.
2. Triple-Play Mode
   • Scenario: The IPTV subnet needs to match the IPTV service subnet on the ISP network, different from the internet service subnet.
   • Configuration:
     • IPTV devices send untagged traffic to port one, which is then tagged with VLAN X and forwarded to the ISP.
     • The VLAN ID for IPTV traffic is set by the network administrator.
3. Advanced Bridge Mode
   • Scenario: Typically used in more complex home network setups where multiple IPTV devices on different floors need to connect through a security router.
   • Configuration:
     • A switch is connected to port one of the router. The switch segregates traffic based on VLANs, allowing IPTV devices to connect to the IPTV subnet while other devices connect to the respective VLAN interfaces.

Configuration UI

The IPTV setup can be found under the interface page in the USG LITE settings:

• Bridge Mode: Simplest setup with no additional configuration.
• Triple-Play Mode: Requires setting the VLAN ID and priority.
• Advanced Bridge Mode: Allows configuring PVID and tagging settings.

Each mode is designed to fit different network requirements and ensure seamless IPTV service.

Traffic Behavior Analysis

Here's a detailed look at how traffic is handled in different IPTV modes:

1. Bridge Mode:
   • Untagged Traffic: Forwarded directly to the WAN interface.
   • Tagged Traffic: Not forwarded to port one.
2. Triple-Play Mode:
   • Untagged Traffic: Tagged with VLAN X and forwarded to the WAN interface.
   • Tagged Traffic (VLAN 10): Forwarded to the WAN interface, other VLANs not accepted.
3. Advanced Bridge Mode:
   • Tagged Traffic (VLAN 10): Untagged out the WAN port.
   • Untagged Traffic: Forwarded to the LAN interface.
   • Other VLAN Traffic: Forwarded to the respective VLAN interface.

Note:

Security policies will not apply to traffic being forwarded from the WAN to the IPTV interface.
