Why Draytek routers doesn’t support MTU1500 for PPPoA?
Posted by on 17 January 2012 04:07 PM


Draytek routers use the same MTU value for PPPoE and PPPoA which is 1492 because MTU 1500 may not be the best value.

Like for example, If you use MTU 1500 and want to access site C and you have to go via sites A and B. All sites should support MTU 1500, otherwise the packets will be fragmented and this may cause problems. (e.g. site C cannot be browsed) .

If you think it is better to allow MTU 1500 for PPPoA, please kindly let me know the reasons then I'll apply a wish for you.

Thank you very much.
