Thanks. I've had a look into it, but I can't get it to work. I tried
this command, which works, but still only shows eth0:

cfgmaker '--if-filter=$default && $if_type==23' --no-down --global
'WorkDir: /var/www/mrtg2' --output /etc/mrtg2.cfg public at

All I want is to see ppp0, also when it is down...
