other things to remember if u have pppoe and a 2.4.x kernel:
you can use pppoe support in th kernel and then use ppp patched
to support pppoe, the difference between this solution and the one described
above is that this one use pppoe support in kernel space ( faster and "securer" )

if you are using iptable you can patch your kernel with tcpmss option
after that you can use mtu to 1500.
