3.3.1 WAN interface
In WAN side, up to 4 WAN connections for following services are supported.
HIS: Internet service
IPTV: VoD and Multicast service
Management: remote management of TR-069 (ACS server)
VOIP: ACS controlled VOIP service. (Currently, its not supported yet)
Only HSI and IPTV interfaces used for routing service for LAN devices. Traffic of
other interfaces is terminated in I-241W-U. IPoE and PPPoE could be configured for
each interface, except IPTV interface does not support PPPoE mode.
Addressing of each interface is individual. Different IP address, gateway and DNS
servers could be retrieved by each interface and used for respective service. Since
both HSI interface and IPTV interface provide routing service for LAN users, either
the gateway of HSI interface or that of IPTV interface must be selected to be the
default gateway for routing traffic and both DNS servers of two interfaces must be
used for DNS queries coming from LAN side.
Only HSI interface supports IPv6.
3.3.2 LAN interface
There is a main interface (called home network interface) used for home network
including 4 Ethernet ports, Dual-band Wi-Fi APs, HomePNA and 2 USB ports.
I-241W-U provides an extra LAN interface (called guest network interface) for Wi-Fi
guest, there is only one Wi-Fi AP of this extra LAN interface. I-241W-U forbids the
traffic between two LAN interfaces, so the packets can not be forwarded between
home network interfaces and guest network interfaces.
3.3.2.1 LAN interface for Home Network (Home Network Interface)
All interfaces (4 Ethernet ports, 2 Wi-Fi APs, HomePNA, 2 USB ports ) are bridged.
The user belonging to home network could reach each other and also use HSI/IPTV
service.
The Web/TR-064 could be used to manage I-241W-U from LAN side. I-241W-U also
supports UPnP IGD and DLNA service.
IPv6 is supported for home network also.
3.3.2.2 LAN interface for Wi-Fi Guest Network (Guest Network Interfaces)
In order to provide Dual-band Wi-Fi guest network for visitors and protect home
network security, an extra LAN interface is provided and two Wi-Fi APs are attached
