Known Affected Releases


Description (partial)

4W 10.5 default port range for IM Desktop Sharing is TCP 49152-65536. Range can be modified, and decreased to 255 ports, but it has to be done at OS level, using a command like this one for instance : netsh int ipv4 set dynamicport tcp start=49152 num=255. It's not possible to decrease port range, nor is it possible to configure the range on Jabber or Cisco infrastructure.
