first, I find icmp packet len 64020 (6,4 MB) , in router,
is this (i think it is) DDOS attack ?!
than i decide to block every packet over 1500,
can this be problems for some normal traffic ?
becouse, i see some packet over 1500, but not much.
btw, we used PPPoE , with MTU/MRU 1492/1492, over wire and wireless.
