Symptom:

You configured a number of providers for ISDN with YaST2. The first dial-in succeeds, but after that, any attempt to connect to the internet using another provider will not give you a working connection. And this in spite of kinternet reporting success.

Cause:

During the first dial-in, the default route is set to the active ISDN device. Later connects via a different ISDN device won't change this.

Solution:

YaST2 creates a file /etc/ppp/options.ipppX (where X is the number of the connection) for every connection configured by it, e.g. /etc/ppp/options.ippp0 and /etc/ppp/options.ippp1.

You have to edit these files. Search for the entry:

# default route should be set by ipppd
defaultroute

Now add the entry

deldefaultroute
It should now look something like this:
# default route should be set by ipppd
defaultroute
deldefaultroute

If you don't want to reboot your system, you now have to restart the ISDN subsystem:

rci4l restart

kinternet might also need to be restarted afterwards.

Note: If you also use and configured network cards in addition to ISDN, you should proceed with caution, as after doing the above changes, existing defaultroutes for the network cards will also be deleted after disconnecting.

Please also note that our installation support will not be able to help you in setting up your network.
