APF Firewall

[Wanch]

When I start APF (APF -s) I see:

opening inbound tcp port 21 on 0/0

I actually see a lot of these for the ports I've allowed. My Question is what is the 0/0? Does it mean it is not opened on no ports?

I'm not sure what it means but mine does the same thing. It still works though. Perhaps the 0/0 is the port (such as ETH0).

It seems odd that is says 0/0. I would expect it to say an IP or port perhaps.
