Hi, there.


I can't manage to find the MTU option on the VDSL DG8045 router.

Does anyone know how to change it?


Thanks.

Hello,

By default, the MTU of an Ethernet interface is 1500 bytes
When ONT is in bridge mode, the Layer 2 MTU of the ONT is 2000 bytes.
When ONT is in route mode, you can set the Layer 3 MTU on the WAN Configuration page. The default Layer 3 MTU is 1500 bytes for IPoE WAN and is 1492 bytes for PPPoE WAN.
You can check the following link for configuration of MTU interface:

Best regards
