Hi,
I didn't really have to configure *anything* as such to establish
connectivity on FreeBSD. The router I have holds the configurations
requried in order to authenticate to the ISP's upstream router.
All I have to do from FreeBSD's view is configure the external interface
to use the router as the default route (using ifconfig or
/stand/sysinstall). That's it.
As your initial problems, what happens if you set mtu to 1500 (or *not*
define this?)? Here's what man ppp says:
set mtu [max[imum]] [value]
The default MTU is 1500. At negotiation time, ppp will
accept
whatever MRU the peer requests (assuming it's not less than
296
bytes or greater than the assigned maximum). If the MTU is
set,
ppp will not accept MRU values less than value. When
negotia-
tions are complete, the MTU is used when writing to the
inter-
face, even if the peer requested a higher value MRU. This
can be
useful for limiting your packet size (giving better
bandwidth
sharing at the expense of more header data).
If the ``maximum'' keyword is used, ppp will refuse to
negotiate
a higher value. The maximum MTU can be set to 2048 at
most.
If no value is given, 1500, or whatever the peer asks for
is
used. A value must be given when ``maximum'' is specified.
What does ifconfig ed0 return? Please post that output here.
Regards,
Stacey
