Thanks
It's working again, I've spent the last 2 days going round in circles on
this thing.
Still I'd like to eventually find out how one goes about setting up a
firewall.

I have the same setup.

My advice is don't use the SuSE firewall setup.  I spent a day trying to
get it to work and everytime I started the firewall I couldn't connect.

So in rc.config:
START_FW="no"

I'm not worried about a firewall yet, as I only have a dialup.  If someone
wants to launch an attack at modem speeds, well, fine.

Anyway, in my wvdial.dod script I have this at the end of startpppd():

    echo "WARNING: wvdial.dod replacing forward ipchain with only MASQ!"
    /sbin/ipchains -F forward
    /sbin/ipchains -A forward -j MASQ -i ppp0
    /sbin/insmod ip_masq_ftp

That's it.

Then in /etc/ppp/ip-up I have

        su moseley -c 'fetchmail -d 60 -M ppp0'

in the ppp0 start section to start reading my email.

Right before I get DSL I'll add to my ipchains.

I'm running a caching only DNS and using sendmail to send the mail.  Dial
on demand works fine.

The next version of fetchmail will allow you to call a sleeping fetchmail
(sleeping because of the -M switch) and connect.  That way I can have it
dial on deman from a cron job and leave fetchmail running all the time.
