TCP ports and firewall settings

If you use a firewall, you must make sure that the TCP port settings on your firewall are consistent with the TCP port settings on the AE Services Server. For information about security guidelines for the AE Services Server, see the White Paper on Security in Application Enablement Services for Bundled, AES on System Plaftorm and Software Only Solutions. This white paper is available with the AE Services customer documents on the Avaya Support Web site: http://www.avaya.com/support.

noteNote

For all AE Services servers, except the Software-Only server, a firewall is automatically configured and enabled by default.

Name Description
CVLAN Ports Unencrypted TCP Port 9999 Enabled/Disabled The port number assignment for unencrypted (nonsecure) connections with CVLAN clients.

This port assignment is enabled by default.

You can enable and disable this port independently of the encrypted CVLAN port. When you enable or disable a CVLAN port, it does not affect CVLAN sessions that are already open.

Encrypted TCP Port 9998 Enabled/Disabled The port number assignment for encrypted (secure) connections with CVLAN clients.

This port assignment is enabled by default.

You can enable and disable this port independently of the unencrypted CVLAN port. When you enable or disable a CVLAN port, it does not affect CVLAN sessions that are already open.

DLG Port TCP Port 5678 The DLG Service uses port 5678 for communication with clients. This is a fixed port number assignment.
TSAPI Ports TSAPI Service Port
noteNote

If you disable Port 450, you must restart the TSAPI Service for the change to take effect.

450 Enable/Disable The port number assignment for the TSAPI listener. By default TSAPI port 450 is enabled. When you disable TSAPI 450, you also disable following TSAPI Port settings:
  • CSTA TLINK Ports for Non-Secured Clients

  • CSTA TLINK Ports for Secured Clients

Local TLINK Ports TCP Port Min Reserved, port 1024
TCP Port Max Reserved, port 1039
Unencrypted TLINK Ports.
noteNote

You must restart the TSAPI Service for changes to the Tlink port assignments to take effect.

TCP Port Min The default minimum setting is 1050. If you elect to use another port assignment as the minimum, it can not conflict with another port number. For information about administering TSAPI Links as either secure (Encrypted) or nonsecure (Unencrypted), see Administering TSAPI Links.
TCP Port Max The default maximum setting is 1065. If you elect to use another port assignment as the minimum, it can not conflict with another port number. For information about administering TSAPI Links as either secure (Encrypted) or nonsecure (Unencrypted), see Administering TSAPI Links.
Encrypted TLINK Ports
noteNote

You must restart the TSAPI Service for changes to the Tlink port assignments to take effect.

TCP Port Min The default minimum setting is 1066. If you elect to use another port assignment as the minimum it can not conflict with another port number. For information about administering TSAPI Links as either secure (Encrypted) or nonsecure (Unencrypted), see Administering TSAPI Links.
TCP Port Max The default minimum setting is 1081.If you elect to use another port assignment as the minimum it can not conflict with another port number. For information about administering TSAPI Links as either secure (Encrypted) or nonsecure (Unencrypted), see Administering TSAPI Links.

You must restart the TSAPI Service for changes to the Tlink port assignments to take effect.

DMCC Server Ports
noteNote

If any of these 3 ports are enabled or disabled the DMCC service must be restarted.

Unencrypted Port 4721 Enabled/Disabled The DMCC Service uses port 4721 for unencrypted communication. By default the Unencrypted Port is disabled. It is provided for backward compatibility with applications that were developed prior to AE Services 3.1.
Encrypted Port 4722 Enabled/Disabled The DMCC Service uses port 4722 for secure communication.
  • By default the secure, Encrypted Port setting is enabled.

  • The default port number for encrypted DMCC communications is 4722.

TR/87 Port 4723 Enabled/Disabled The AE Services Server uses port 4723 for the AE Services implementation for Microsoft Live Communications Server. By default this port is disabled.
  • You must enable this port if you are integrating AE Services with Microsoft Live Communications Server.

H.323 Port TCP Port Min The default minimum setting is 20000. The DMCC Service uses this port for signaling.
TCP Port Max The default maximum setting for this range is 29999. The DMCC Service uses this port for signaling.
Local UDP Port Min The default minimum setting is 20000. The DMCC Service uses this port for Registration Administration and Status (RAS).
Local UDP Port Max The default maximum setting is 29999. The DMCC Service uses this port for RAS.
RTP Local UDP Port Min The default minimum setting is 30000. The DMCC Service uses this port for the Media Real Time Protocol (RTP) sessions.
RTP Local UDP Port Max The default maximum setting for this range is 49999. The DMCC Service uses this port for Media RTP sessions.
SMS Proxy Ports Proxy Port Min Enter a Communication Manager proxy port range of up to 16 proxy ports. By default, the Communication Manager Proxy Port Range is 4101 to 4116.
noteNote

SMS can use up to 16 ports. If you change any of the SMS port assignments, make sure that there are no conflicts with other ports.

Proxy Port Max Enter a Communication Manager proxy port range of up to 16 proxy ports. By default, the Communication Manager Proxy Port Range is 4101 to 4116.
noteNote

SMS can use up to 16 ports. If you change any of the SMS port assignments, make sure that there are no conflicts with other ports.
