If you are using iijPPP, I would make sure and get the patches Doug Rabson just committed to the -stable tree as they greatly enhance the b robustness of it. > 1) I thought I had seen discussion in the mail list archives on doing 'arp' > commands when using iijPPP on dial in lines.

Sure, but the other machines on the same network don't have a route to the box. > 2) The link to my provider is started on boot.

Not using iijppp. You may want to get my 'ddial' patches to iijppp, which cause it to always keep the link up, but they *require* the stability patches above because it triggers some of the bugs it fixes. > 3) In /etc/sysconfig, I ifconfig lo0, ed0, and tun0. iijPPP auto-configures tun0, so there isn't a need to do that. > Everything works fine, > but why don't I have to add lines for tun1 through tunx?

You don't. > 4) In /etc/ppp/ppp.conf, each label has the appropriate 'ifaddr' entry.

Because you're relying on your remote boxes to setup the addressing. Nate
