The larger and more complex your on-prem SfB installation is, the greater the likelihood of encountering firewall problems.

If you run this script on your Front-End server(s) it will:

  • query the topology to find all of the Edge servers. (Add the “-site” switch to only retrieve those in a given topology site)
  • initiate a TCP probe to all of them on all the ports that should be open: 443, 4443, 5061, 5062, 8057 & 50001
  • output the results to screen
  • output the results to the pipeline as an object
  • save the results in the log file in csv format

The one thing it won’t do is attempt a UDP connection to port 3478. (OK, and yes I’m figuring if 50001 is open, so will 50002 and 50003).



Download the script from the Technet Gallery site.
