To use itrezzo, there are firewall permissions that must be set. Use the following guidelines to set your firewall permissions:
- Turn off the Windows Firewall on the server running itrezzo UCM.
If your organization cannot afford to keep the Firewall off, then the following ports must be open:
- Port 80 – It is used to run the itrezzo Web Admin locally.
- Port 443 – Required to make EWS calls to and from the Exchange Servers.
- Port 389/636 – itrezzo UCM uses either LDAP on port 389 or Secure LDAP on port 686 via TLS to read Active Directory information. Note this firewall port is not needed for cloud only users.
- Open all high-range ports (ports 49241 and up)
