Could you elaborate a bit more on the "mtu issue"s you have seen?

MTU, MRU and broken PPP clients *are* a very icky topic, but what I've
seen so far, 12.3(10) seems to be really well-behaving (I did a lot of
testing on L2TP with PPP MRU negotiations and MTU settings recently, and
the worst thing are "client PPP implementations" - but Cisco's side
did the correct thing).

(Ever seen a client NAK a CONFREQ with MRU setting?  LNS says "my MRU
is 1492", client says "no, you must use a MRU of 1450" - doesn't make
any sense at all, but then, it's just a windows machine...)
