...and, finally, make sure that you have masq entries for *both* sl0 *and*
ppp0, as diald changes the default route as it brings the link up.
If you only have a masq entry for sl0 (i.e. -W sl0) then you'll be able to
bring up the link but won't be able to send any traffic once it's up.
If you only have a masq entry for ppp0 (i.e. -W ppp0) they you can only
send traffic if some other traffic brings the link up.
