Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I'm trying to access a remote FreeNAS box, with AFP sharing set up, from a Mac. (AFP works fine over the LAN, just not over WAN.)

From a remote location, if I go to Finder and Go>Connect to Server then enter afp://myserver.com, I get prompted for username & password, and then am presented with list of shares, just as over LAN.

However, when I choose a share, there's a little spinner in the bottom of the window; it spins for a few seconds, and then my machine is OUT COLD. I.e., frozen, halted ... not black screen, but NOTHING works except moving the cursor around. Cannot Apple-Option-Escape, cannot Apple-Tab, cannot click anything. Only option is hard reboot.

I tried this from both a MacPro running 10.7.4, and MacBookPro running 10.6.8, and had the same result.

On the FreeNAS side, it's a FIOS connection, using a Verizon MI424WR-GEN2 modem, where I forwarded port 548 (TCP & UDP) to the FreeNAS server. (Obviously I'm getting through fine, since I'm being prompted to log in and getting the list of shares.)

I'm 96% sure this DID work before we switched to FIOS over there ... when we had DSL.

I checked Console but didn't see anything that seemed relevant.

Now here's the weird thing. If I try to access the share with our static IP address, it works perfectly! And if I try to access it via a Dynamic DNS alias we have set up through dyn.com, it works!

The URL which I want to be using is set up as an A record in our DNS at Dreamhost.

I'm completely baffled.
