I’m trying to optimize my network to make most efficient use of my limited bandwidth. Part of that optimization is to ensure that my client send packets which do not amplify over the WAN links (in other words not fragmenting).
I’m on DSL connections (3 I’m trying to bond) my PPPoE interface MTU is 1492. I have SpeedFusion running which should take some overhead to send down the tunnel. My goal is to ensure that SpeedFusion never has to send a partial fragment down one side or the other as a result of a single packet being sent by the source. This should in-theory prevent the additional header send down the congested DSL lines for a packet fragment remainder (which on a 1500 MTU normal is only ever 80-100 bytes at best).
Can anyone tell me what the optimal MTU size to configure my computers and network for in order to prevent fragmented sends over PepVPN/SpeedFusion?
