It's because the masq module isn't as smart as it could be. When a packet
or fragment thereof comes in destined for the internet, the masq module
makes the required changes to its return address and forwards it on. If the
incoming packet on your eth0 (MTU 1500) is bigger than can go out your ppp0
(MTU 294) then it will drop it instead of letting it it fragment more.
So now you know, and knowing's half the battle.
