>Description:
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
