Guy,
We solved it by ading the mtu 1452 mru 1452 in the pppd command. The
ethernet may stay mtu 1500.
more over, if you set the ppp mtu = eth mtu you might create fragments (as
the ppp sends data to pptp and pptp adds its own header, thus ecceeding
the ppp = eth mtu.
Can Alcatel / ATUR3 if this
someone sent an article on one of IOL's forums, regarding disconnection
problems with orkit's ADSL modems. he claims the problem is most likely a
bug in the fragment handling "code" in orcit's modems, and is solved by
reducing the MTU to 1432. here is the link to the article:
