I have a software firewall program installed on my computer
Add the Jungle Disk program to your Exceptions list for your Firewall.
I have a network-based firewall and/or a firewall that does not allow program exceptions
In this situation, you can add our servers/ports as exceptions for your firewall so that the firewall allows these connections through your network.
We use ports 443 and 80 through your network for Outgoing traffic only, so if these are already open, no further actions are necessary.
Note: While Jungle Disk does make incoming connections, it only makes them from the Jungle Disk application (the GUI) to/from the Jungle Disk Service (background program) within your computer and only if you're using Jungle Disk Simply Backup, Desktop, or Workgroup.
Note: If you are working with a hardware-server that does not support domain/url-level exceptions, you will need to open ports 443 and 80 (Outgoing-only)
