Those Parameters are allready set in the pppoe options file.
The problem with his setup seems to be that the "server" here the bering box
starts sending the LCP ( echo requests) and that those aren't answered within
the LCP-echo-interval. After 3 tries exactly that happens what you described,
namely the server gets no response and supposes the line ( connection) is dead
and does an hangup.
unfortunately the whole pppd is stopped, also takeing down the dialout part on
ppp0.
Interesting is why
1 the client doesn't answer the lcp-echo requests.
a--They don't reach the client (firewall /route issue locally or on
client.)
b -The client answers but sends them over a wrong interface or the outgoing
answer is blocked . ( route /firewall )
if the client is also a bering box it could be that the external interface is
declared as eth0 and not as pppo for example
c- the server is blocking the answers on the firewall
(remember that now the ppp1 is also an external interface).
Troy might setup the shorewall rules to log all incoming and blocked traffic.
or clear the firewall for the test.
