I'm looking for guidelines about MTU to be chosen for wireless PPPoEconnections.
Actually I've configured it @ 1480.
I would like to know if it might be optimized, considering several factors (rtt, latency, etc..).
My has MK as PPPoE concentrator and OSBridge as CPE at customer's site. What happens is that if I let CPE authenticate on MK as PPPoE client, some web sites do not work; if I use PPPoE auth on customer's PC, behind the CPE, everything is ok. Strange behaviour...
