next in thread | raw e-mail | index | archive | help
We just got a DSL connection and I am having a slight problem with
ppp/PPPoE not recognizing a lost connection and renegotiate a new IP
address. For example, if I reboot the DSL modem or unplug/plug the line
back in where the remote ppp connection is lost, ppp doesn't recognize
this and still associates the old IP address with tun0. Isn't PPPoE
supposed to recognize a "carrier" lost? It seems to never notice when I
reboot the DSL modem (or just turn it off). This is obviously not ideal
if the remote ppp session ever went down. Any suggestions? This is what
we have:
1) FreeBSD -stable (4.5-PRE)
2) Alcatel 1000 Ethernet DSL modem, connected to xl0
3) internal network connected to fxp0
4) my ppp.conf looks like this:
DSL:
set device PPPoE:xl0
# set MRU 1490
# set MTU 1490
set authname ...
set authkey ...
set dial
set ifaddr 10.0.0.1/0 10.0.0.2/0
add default HISADDR
nat enable yes
# set cd off
# set crtscts off
5) ifconfig -a looks like this:
