RRM> 1) Have you told natd the interface is dynamic and might change IPs? Yes, of course. RRM> 2) If you're using ppp, why even bother with natd?

I can tell you this helps a lot when trying to use RRM> dynamic rules. That's a great idea! I had not considered it until now. I would just need to work the anti-spoofing and private net rules into the ppp nat process somehow. I guess, I would have to use ppp filtering just for those rules. If I can do that, your way does seem to be a good place to start in resolving my error messages. Thank you very much for your help!
