I've been having to count the rules out to put in the whole number. From David's message, I had assumed that a xx50 format would automatically order the rule at a step of 50. Doesn't look that way. Oh well. It'd be nice . . . And I've been to onlamp. It did have a lot of info I didn't find in the handbook. Mostly a lot of clarification on details that were there. > It's the O'Reilly Network BSD Dev Center FreeBSD Basics section and is > really helpful on setting up firewalls using ipfw.

Exactly. I've read a couple of them so far. The thing is they are so long that they require some uninterrupted time to keep focus. Not light reading, but very informative. Time to focus on a couple natd resources. Anyway, I tried a slightly modified version of Dan O'Connor's example at mostgraveconcern.com, which I swear hosed my connection before, and it came up fine this time. No nat still, I'm getting a failed to write packet back (Permission denied) error from natd in /var/log/security.
