Hey ...
You're on dsl aren't ya?

You wouldn't happen to be using PPPoE would you?

IF you are using PPPoE ... Roaring Penguin's RPpppoe scripts do a great job of handling that ... in their case they have the MTU set up in the scripts for the ethernet and ppp connections

If NOT .. ifconfig ethx [ipaddress] MTU=1496 up
will bring up the interface ethx with whatever ipaddress and an MTU of 1496

Point to be made .. in the linux world, and with pppoe the ETHERNET card conected to the dsl modem MUST have an MTU of 1500. The DSL MTU is set on the PPP connection instead. HOWEVER to improve throughput and handling processes the OTHER ethernet connections to the box should have the MTU set to [isp suggestion - 40] for an MTU and the other connected boxes should also have their MTU capped.

The reason for the -40 there is the 40 bytes of packet header that must be added on to the ethernet packet to put it in the dsl pipe.

Dude, go to http://www.dslreports.com join their forum and ask someone in the linux or the tweaking forum. Thats where I went when I needed help tweaking my dsl connection, and they worked great.

All it is is a matter of editing one file, but I forget the file........
