Services: what ports do I need to forward?

[michaelsanford]

I need access to AFP, among other services, from the WAN to my iMac behind a NAT. Right now I have all the ports listed in the Sharing pane's Firewall configuration table mapped to my server...

Essentially I want to know if all those ports are really necessary, or, if like passive FTP, only one is per service.

Right now I have:
• Personal File Sharing (548, 427)
• Printer Sharing (631, 515)

Thanks!

I would suggest to try with port 548 alone as pointed out there.

Cool, thanks.
