If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are 
willing to experiment, you can gradually reduce the MTU from the maximum value of 1500 
until the problem goes away. The following table describes common MTU sizes and 
applications. 

1500

The largest Ethernet packet size. This setting is typical for connections that do not use 
PPPoE or VPN, and is the default value for NETGEAR routers, adapters, and switches.

1492

Used in PPPoE environments.

1472

Maximum size to use for pinging. (Larger packets are fragmented.)

1468

Used in some DHCP environments.

1460

Usable by AOL if you do not send or receive large email attachments, for example.

1436

Used in PPTP environments or with VPN.

1400

Maximum size for AOL DSL.

576

Typical value to connect to dial-up ISPs.

 

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. 

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).
