Configure Firewall

From AwkwardTV

[edit] Note

The AppleTV seems to ship with no firewall rules configured. There is no need to hack up a way to disable the firewall.

In MacOS X, at boot time,

/usr/libexec/FirewallTool

runs, which reads the file

/Library/Preferences/com.apple.sharing.firewall.plist

Neither the binary nor the plist are distributed with the AppleTV OS, and it is therefore not surprising that in a default OS install, the ipfw kext has a single 'allow any' default rule:

-bash-2.05b$ sudo ipfw list
65535 allow ip from any to any

[edit] Enabling the Firewall

It is likely that copying over FirewallTool from an Intel Mac will enable MacOS firewall configuration at boot time. In addition, it is neccesary to create /Library/Preferences/com.apple.sharing.firewall.plist. If the prefs plist file does not exist, FirewallTool will not configure ipfw. There are several ways to create this file:

• Copy one you like from an Intel Mac
• Copy one, then edit as you like with the Property List Editor that comes with Xcode. (see: MacOS Hints article)
• Install System Preferences from an Intel Mac and configure as usual.
