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:

tim@gw [1:23am] ~ > ifconfig -a
