Port Mapping OS X Server, Once and for all…….

I'm going out of my mind here, I've been trying to set up port mapping for years, last night I spent hours doing it. You can't modify natd.conf cause apple will overwrite it. I tried making a custom natd.custom.conf file, and starting natd using it manually, but when I did, my whole internet would go out. I tried setting the options in the natd.plist using apple's crazy xml format, and when i load my settings in, natd just won't start, though it won't tell me why. But I can assume its because I leave the alias IP blank, since my external IP is dynamic. In real natd.conf, you can leave alias out you just have to specify the interface "en0". I tried all sorts of variations of that, but NOTHING would work! I even tried using BrickHouse at one point but that thing totally messed with my config files and cause all sorts of problems. In the end, i used Webmin to set up my firewall rules, and I just need to map a bunch of ports and I'll be good to go! And I'm starting to get really pissed at apple, if they weren't going to put a real port mapping GUI into the natd panel, then they should have left natd alone so we could edit its config file normally.
