TCP/UDP Ports used by Time Machine

Hi,
Does anyone know what TCP and/or UDP ports are used by Time Machine? I might have to access my Time Capsule through a firewall and wanted to know what ports I need to open on my firewall

Thanks

MacBook Pro 2.2 GHz, Mac OS X (10.5.3)

Hi
So i too discovered... But I would like to do filesharing over the itnernet and thus use portforwarding to do so. However this port is already in use and cannot be forwarded! >Do you know if this can be solved?

I doubt TM uses an TCP/UDP ports since it isn't an internet application. Time Capsule uses Ethernet directly. However, here's Apple's info on the topic: "Well Known" TCP and UDP ports used by Apple software products.

Well, if Time Machine can connect to Time Capsule using ethernet, then that would infer that Time Machine uses tcp/ip to communicate with Time Capsule?

I backup my MacBook Pro using gigabit ethernet, i'm not using wireless. I did a port scan of the Time Capsule and it had these open TCP ports. I need to use another machine (to do a UDP scan)

Open TCP Port: 139 netbios-ssn
Open TCP Port: 445 microsoft-ds
Open TCP Port: 548 afpovertcp
Open TCP Port: 5009 winfs
Open TCP Port: 10000 ndmp

NDMP is not a TCP port that is listed on the link that you provided.

I guess I can just test it out and report back my findings... unless someone already knows the answers.

The tcp port used to communicate between Time Machine and Time Capule is TCP 548. AFP over TCP. There is no UDP communication.

That's the standard AFP port. It is on the list. Thanks for verifying the information.
