F/W 1.11 - Fibre 400/200: MTU Setting
The default MTU sizes for different network topologies Apr 17, 2018 Best DSL MTU not 1500? - SpeedGuide Dec 02, 2011 How can I optimize PPPoE connections? | SonicWall It is generally recommended that the MTU for a WAN interface connected to a PPPoE DSL network be 1492. In fact, with auto MTU discovery, 1492 is discovered to be the maximum allowed MTU. However, having an MTU of 1452 is most optimal. NOTE: To change the MTU size on the SonicWall UTM appliance refer to How to change the MTU size.

networking - MTU 1500: fragment packets after 1472 bytes I have couple of VMs running on Openstack. I have one data network gateway assigned into the switch with MTU=1500, where VMs has to running. Also in Openstack, I have set the default MTU=1500 of the network. I am trying to ping from the VM to gateway (OR any ip on same network) of the switch with 1500 packetsize, it's de-fragmenting the packet.
Note: For information about why the MTU size is 1492 bytes, refer to the PPPoE Baseline Architecture for the Cisco 6400 white paper. The problem occurs because many web servers block ICMP messages, which causes the server to continuously send 1500-byte packets. These packets are dropped, and as a result, the requested web site does not load.
Maximum MTU for PPPOE - Plusnet Community Windows machines from visa on will auto determine the MTU and would match the router setting. @Oldjim For what it's worth: Plusnet TG582n router will by default use a MTU of 1492 when configured for pppoe (fibre). When configured for ADSL it defaults to a MTU of 1500. Don't know about the 2704n. networking - MTU 1500: fragment packets after 1472 bytes I have couple of VMs running on Openstack.
