Hello misc@,
I have a OpenBSD-based router. Its configuration:
rl0 is connected to internal network in my flat
rl1 is connected to home network (several flats) - some local servers
are located in that network
rl2 is connected with ADSL-modem - Internet access
ath0 is wifi - wireless AP in my flat
Detailed configuration (ifconfig && /etc/hostname.*) will be below.
Till some time everything seems to work pretty fine. This week I have
noticed that my Internet connection sometimes disappears.
route show -inetshows that there is no default route (but it is added
during the initialization of pppoe). sh -x /etc/netstart pppoe0 does
not help - error message says
route: writing to routing socket: Network is unreachable
add net default: gateway 0.0.0.1: Network is unreachable
Restart quickly fixes the problem. Other solution is to add manually
default route. E.g. in case I have IP 78.37.32.133 and connected to
Internet via 78.36.32.1, then command
route add default 78.36.32.1
fixes the problem for a long time. BTW, ping to 78.36.32.1 passes
normally in any case (even if the default route is not set).
Well, any ideas what could be the problem? Of course I can write a
simple script which will get this IP (ifconfig pppoe0 | sed ...) and
then sets the desired default route. But I think this is not a correct
behaviour, so I would like to fix that in a right was.
Detailed configuration below.
