MTU size PPPoE / WAN
Sliderhome Newbie ✭
Why is there no option to set the MTU size for PPPoE to 1508 and WAN X1 to 1512
Our ISP uses MTU 1500 to pass through the PPPoE connection.
On the Ubiquity routers, we set PPPoE MTU size to 1508 and WAN port to 1512 (PPPoE 8 bytes + VLAN 4 bytes).

You'd have to enable jumbo frame support before you can configure MTU sizes greater than 1500 bytes.
Thanks for the answer, only the TZ Sonicwall Series don't have this option.
Raise a feature request for RFC4638 support with Sonicwall. Would be great if you could do that from here but they usually refer you to your account manager for some reason.
