index | next in thread | raw e-mail
Hi
I've installed and configured a fairly recent version of user-ppp with
mgetty and Auto-PPP support (on a 2.2.5-R machine).
I would like to have an on-demand PPP-link beetween two IP subnets A
and B (via modem). The FreeBSD machine sits on the B network.
|A network|--|modem|<---POTS--->|modem|--|FreeBSD / B Network|
I have configured the ppp-daemon in "-auto" mode to enable on-demand
connection from B to A : it works.
I have configured mgetty and PPP to enable incomming PPP connections
from A to B : it works.
When I try to authorize both incoming and outgoing connections through
the same modem, it stops working : on-demand outgoing PPP -auto takes
hold of the line and mgetty is kept out of the picture (and can't
answer the line).
1st question : is there a configuration of mgetty and "ppp -auto" so
that they share a single modem ?
2nd question : (if two modems are needed) doesn't the TCP-IP stack get
confused with having two interfaces for the connection beetween two
networks ? (each with unidirectionnal routes when the line is down)
Thanks in advance for your help
