Hi,

Anybody got experience with some mtu issues and using adsl?
Things work allright, even the vpn works allright between
two networks but sometimes connections arent comming through
and are dropped. (netbsd setup with racoon and adsl connection).
I cant find any mistakes in the config files and normally it works like
a charm. Oh yes... the connections which arent comming through
are from internal m$ machine which always have their DF set.
Only thing i can think of is that sometimes fragmentation is needed
to encap the packets and send it to the other network and with the
DF bit that isnt possible. Though, i would expect icmp 3,4 back then....
I am sure the tunnel is set up nicely and everything works fine.
Its just that m$ machines got trouble.
Only difference i can see is the df bit, so i figure mtu issues come 
into play. Anybody got similair experiences?
Bye,

Mipam.
