willing to experiment, you can gradually reduce the MTU from the maximum value of 1500
until the problem goes away

applications.

Enable the Bridge or Add a VLAN Tag Group
Some devices, such as an IPTV, cannot work behind a router’s Network Address Translation
(NAT) or firewall. Based on what your Internet service provider (ISP) requires, to allow the
device to connect to the ISP’s network directly, you must enable the bridge between the
device and the router’s Internet port or add new VLAN tag groups to the bridge.
Enable the Bridge
If your device, such as an IPTV, is connected to the router’s Ethernet port or WiFi network,
you can enable the bridge so that the packets sent between the device and the router’s
Internet port are not processed through the router’s Network Address Translation (NAT).
To enable the bridge:
1. Launch an Internet browser from a computer or wireless device that is connected to the
network.
2. T
ype http://www.routerlogin.net or http://www.routerlogin.com.
A login window opens.
3. Enter the router user name and password.
