Hi
How is it that I can connect to my office machine (late 2104 iMac) via Back To My Mac from my MacBook when I am a few rooms away, but not when I travel further afield?
Many thanks
iMac, OS X Yosemite (10.10.3)
You'll have to talk to the office people in charge of the network about possible double NAT situations, and/or proper configuration of uPnP across the network. Make sure that the TCP or UDP ports used by Back to My Mac are open on your firewall.
For all lines except for 49152– 65535 UDP
Just put, for instance, 443 - 443 TCP
Really grateful for your help. I've entered all the ports, now just need to go out and test it!
Hi - yes it is but I am still getting a 'cannot connect' message, so not sure what to try next?
Many thanks
No, you need to open:
443 TCP
500 UDP
1900 UDP
4488 TCP
4500 UDP
5223 TCP
5350 UDP
5351 UDP
5353 UDP
49152– 65535 UDP
