PPPoE and DSL: Using 'adsl-setup' I configured the DSL files which are stored in /etc/ppp I selected '1' for normal firewall settings. 'adsl-start' could not establish a connection and timed out without additional error messages. I found out that the two files which describe the firewall settings are missing (firewall-standalone, -server). My solution: I got them from www.roaringpenguin.com (they can be found in the .tgz distribution), if they are put it in /etc/ppp 'adsl-start' can establish a connection with firewall settings. Without the two files, connection can be established if one selects '0' (for no firewall) using adsl-setup
Please verify this with a newer version of Red Hat Enterprise Linux or Fedora Core and reopen it against the new version if it still occurs. Closing as "not a bug" for now.
