Guys... don't mess arbitrarily with link MTUs (RA) when you have
problems with path MTU.
I believe we've had this discussion before, and it seems to be quote
subjective.
Personally I prefer to lower my home LAN MTU to my tunnel MTU so as to
avoid having to do PMTUD adjustment on all traffic (my concern was mostly
remote->me large packet that incurs an additional RTT for each
connection).
I seem to remember you differed in opinion. :P
