This weekend I have activated the Apple Filing plugin for my OpenMediaVault server in order to improve the overall experience in accessing data from my MacBook. Due to the fact that the firewall on the OMV server is enabled and drops all incoming connections by default, I had to open the ports used by Apples Filing Protocol manually.
|427||TCP||Service Location Protocol (SLP)||Network Browser, Authentication|
|523||TCP||Apple Filing Protocol (AFP)||Apple File Service|
|5353||UDP||Multicast DNS (MDNS)||Service Announcement|
