I am running a PPPoE server on RouterOS, my PPPoE clients are mostly Windows machines.
Here's my doubt:
I know that PPP has an overhead so I must adapt the MTU/MRU but, this adjustment must be done in the PPPoE server running on RouterOS (eg. lowering MTU/MRU from 1500 to, say, 1480) or I must leave the MTU/MRU in 1500 on the server and only change it in the clients?
The MT documentation doesn't say much about it (the example shows the server running with MTU 1500).
What your practical experience says in this matter?
What are the most efficient values? 1500? 1480? 1492?
