Cannot connect to ARD client v3.7 with firewall enabled

Im having the exact same problem, a mac mini running 10.8.5 server, i put ard 3.7 on it to control 10.9 machines, after it rebooted i can no longer control it. I can send commands to it via ard, but thats it. Going to try this, thanks

I also have this problem on a network of about 28 Macs. Upgraded to ARD 3.7. Running 10.8.5.

Most Macs are accessible via ARD as always, but some fail exactly as you describe. If the firewall on the client is disabled then ARD can access the remote machine OK.

This looks like a flaw in ARD 3.7 to me.

Have not yet upgraded any Macs to Mavericks.

Yep its the firewall alright, can now access the 10.8.5 server again. They need to fix this fast

Same as mine

Same problem here on a MacBook Air, same workaround fixes it. Bummer.

I think I have a solution/workaround that allows the firewall to be ON.

On the client machine, go to firewall options, scroll though the list and look for screensharingd.

Make sure it is set to Allow incoming connections.

Turn the Firewall OFF.

Restart the client Mac.

When restarted turn the firewall ON again. At this point I was asked if I wanted screensharingd to allow connections (even although I had already set it to do so), and so you may have to set this option a second time.

Now try ARD from the adminstrator Mac. This worked for me, and allows remote management with firewall ON.

I hope this helps: interested to see if it does.

yep, Ive rebooted mine several times to test, still there

Unfortunately, it doesn't appear to work after a reboot for me.

I think all I have achieved is a way restoring ARD access with the client firewall ON, but only for that particular session. Even when using the padlock on the firewall tab to prevent further changes, screensharingd reverts to Block incoming connections. You would have to reset this each time, which is hardly ideal.

Here's a bandaid until Apple figures out what exceptions to add to the firewall

Hi

Just opened up firewall unlicked it and in advanced screensharingd was set to block incoming connections sett to allow Ok'ed and ARD now has control after multiple re-boots. seems to all be good. Not sure whey screensharingd needed to be turned on as under ML i assume it was off and ARD worked fine.

Does it continue working after you restart?

Yes, I did it and it works pefectly! Thanks for sharing it.
