I am trying to make ports on my OSX 10.6.5 mbp accessible to the open internet.
The only thing I could find in the system firewall was allowing (or disallowing) a particular.app file, but nothing about specific ports. From Googling I read that the firewall is supposed to let an allowed.app use any ports it wants and specification is not needed. I added the .app I wanted to add the port for.
The router is an Airport Extreme v7.5.1.
I've created a DHCP Reservation based on wireless MAC for the laptop, 10.0.0.5.
Under Advanced : Port Mapping, I added a new entry with the same values for each combination of fields:
Public/Private UDP/TCP Port: 9000 Private IP Address: 10.0.0.5
I want port 9000 on my public IP address to forward to port 9000 on internal IP 10.0.0.5.
When I test my application after this, it doesn't work.
To further test, I've turned off the system firewall on the laptop, and I've also placed the laptop in the 'DMZ' by checking Enable default host at: 10.0.0.5
Even with this configuration set (disabled firewall in the dmz), a full port scan from GRC Shields Up!! reports no ports open whatsoever. Is that normal for OSX? I come from Windows-land, so that would be a surprise.
Is something wrong here?
