Hello,

I am trying to set up BIND/named to host my own DNS. I appear to have a blocked port but ipfw is pleading innocent. I have set up a port forward ('virtual server') on my router; public port 53 to private port 53, TCP and UDP. I'm have turned the firewall off completely in the prefs panel.

Code:
/etc$ sudo ipfw list 
65535 allow ip from any to any 

/etc$ nc -vz x.x.x.x 53    (my external IP) 
^C    (hangs) 

/etc$ nc -vz 127.0.0.1 53 
Connection to 127.0.0.1 53 port [tcp/domain] succeeded!
Can anyone suggest what the next step to look at might be?

Thank you,
Darren

Is named actually listening on the external address?

netstat -an | grep LISTEN

I got it sorted, thank you for the suggestions!

I have a modem, and a wifi router behind it. I was forwarding the port from the router to my Mac, but not from the modem to my router.

Cheers :)
