Service Ports

Each service is bound to one or more IP addresses and port number.

These can be changed if required, however, IceWarp Server's default ports conform to Internet standards which are commonly defined in client applications and may be required by your ISP.

Most installations will work correctly with the defaults.

If you are using a Firewall you must open the TCP ports for all the services you are using.

Warning: IceWarp Server's POP3 and IMAP run as one module, so if you stop this module, both services will also stop.

The same applies for IM and SIP.

You should also be aware that IceWarp WebClient and FTP run under the Control service. If you stop or restrict access to the Control service your users may not be able to use IceWarp WebClient or FTP.

note_small

You may also need to set specific IP binding of the machine the server is running on if that machine is running other, non-IceWarp Server services (IIS, for example) as IceWarp Server will bind to all available IP addresses. The same port/IP cannot be used by more then one server software.
