Description Meulemans Jeroen 2004-09-07 18:10:20 UTC 
Have server with 3 network cards:
* rl0: cable
* rl1 => tun0: ADSL
* xl0: internal

Made a script that makes you able to switch between ADSL and cable internet. The switch works perfectly, but after 5-7 days the default route magically disappears (route get default). If the server gets restarted and the ADSL is active from the start, then it will work forever. If I use the switch script it doesn't.

How-To-Repeat: Have tried it on FreeBSD 4.8-4.10 (problem is always there)

killall -KILL dhclient
killall -KILL natd
ifconfig rl0 delete
ppp -ddial ADSL_ISP > /dev/null
natd -dynamic -f /etc/natd.conf -n tun0
internet works perfectly but goes down after 5-7 days
if I switch from ADSL to cable same problem

check ppp.log pls. I suspect ppp deletes the route, which it created before.

Last log in ppp.log always dates from the moment the succesfull connection
was made. 5-7 days later, the default route fails (disappears) without any
notice in any log files (neither in ppp.log) .

Thanks,

Bringing an interface down will blow away all routes through this interface,
including "default".  Are you using the "sticky" default route in ppp(8)?

I am using the sticky default route, here is my ppp.conf:

default:
  set log Phase tun command # you can add more detailed logging if you wish
  set ifaddr 10.0.0.1/0 10.0.0.2/0
SCARLET:
  set device PPPoE:rl1
  set authname USERNAME
  set authkey PASSWORD
  set dial
  set login
  add default HISADDR

Thanks,
