#The wan interface needs to be set to an MTU of 1508 on the assumption that there needs to be room for the 1500 mtu PPP package on the way to the modem (1500 may work - untested though). #You will require the unreleased ppp 2.4.6. In testing, ppp 2.4.5 with the rp-pppoe plugin updated to the latest version seems to work, although a recompile will be necessary. This can be fetched from ppp's website / git. #Using ppp's debug option will allow you to see the rp-pppoe plugin negotiating a PPP-Max-Payload option with the BRAS via ana ~~LCP~~PPPoE option. If this isn't seen, then your MTU is forced back to 1492. =RFC 4638 on OpenWRT 10.03.1 (Backfire)=
