The environment:
Dell Optiplex GX110
192MB RAM
Ethernet on motherboard
5610 USRobotics Modem PCI card
Jaunty 9.04 - Desktop environment

So the modem is working, but traffic is denied when ufw is on. Oddly, this is not the case with the ethernet connection.

I've installed the gui Gufw.

Does anyone have a set of general rules to allow the dialup modem connection to work, along with standard web/ftp/mail clients that I can import? (Firefox, Gnome PPP, wvdial, Evolution, Filezilla, Traceroute, Ping, etc.)

The interface is unlike other firewalls I've dealt with. The man gives some examples, but why reinvent the wheel?

Any help will be greatly appreciated.
