Manage which communication ports are open?
I have an iMac 5K and bought the game "Tom Clancy's Splinter Cell Conviction" for it, but it doesn't work. A message pops up claiming the game simply can NOT connect to the internet. Hmm. Every other function of the computer and other games seem to have zero problems connecting to the internet when needed.
I contacted Ubisoft and they send a rambling set of Must-Have conditions back that included the semi-opaque step:
2. If it is not possible to shut-down your firewall, you will need to configure your router or firewall to allow the following network ports for the best possible connection:
Uplay Required Ports:
TCP: 80, 443, 13000, 14000, 14008
Directions for configuring network ports are specific to the software and hardware being used, and can be found by visiting the manufacturer’s website.
The firewall is off in my System Settings>Security>Firewall, so, perhaps it's a Port setting? Are the ones mentioned any different from the iMac normal or default ones? If so, where would I check/change them to comply with the game's requirements?
I can connect to the internet through my older flat-body Airport Extreme or through my U-verse router, and both ways exhibit the same fault.
Leticia @ Ubisoft's finger-pointing continues, claiming the fault is "applications running in the background" or "certain restrictions set by my ISP" but that sounds like complete hooey.
Any help would be appreciated.
