Note:
1. If you enabled both options mentioned above, then note
below: (a). Set IPTV set-top box's connection type to
DHCP/dynamic IP or static IP (IMPORTANT: Note that the
set-top box's IP address should be on the same IP net
segment as router's LAN IP.) if the set-top box is connected
to any port of LAN ports 1-3. (b). Select the dialup mode
provided by your ISP if the set-top box is connected to the
IPTV-specific port.
2. After the IPTV port is set for IPTV purpose, PC that connects
to such port will not be able to obtain an IP address or
access Internet. So think twice before you start. Plus, LAN
ports1-3 can only be used as LAN ports to connect PCs
instead of an IPTV set-top box.
