Configuring an AppleTalk Server in Linux

In general, AppleTalk should be used on trusted networks. If you are running a firewall on your netatalk server, however, you must open access to several ports for netatalk to work. In particular, you may need to open ports 548 (AFP over TCP/IP), 201 (AppleTalk routing), 202 (AppleTalk name binding), 204 (AppleTalk echo), and 206 (AppleTalk zones).
