Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

My questions are:

  • Do I use "pf" or "ipfw"?
  • How do I forward traffic from port 80 (HTTP) on the external interface (en0) to port 8080 on localhost (
  • How do I allow traffic on port 22 (SSH) from any IP address?
  • How do I allow traffic on port 8100 from a specific IP address?
  • How do I make all this persistent, so the rules get applied when the system boots?

I am running OS X Server 10.8.3.
