Firewall

Firewall

ClassiX® communicates via TCP/IP with ObjectStore and other ClassiX® instances (remote messages). The following describes the settings of the local computers (ObjectStore server and ClassiX client). If there are other firewalls in between, ports 51025/TCP and 51031/TCP must be opened accordingly.

A firewall, including the built-in Windows firewall, should be configured in this way (please note that each firewall must be configured differently. The steps given below are described as examples under Windows XP and must be adapted according to your firewall):

Client

  • The computer must accept incoming connections on port 51031/TCP. The ObjectStore Cache Manager accepts the connections.
  • For remote messaging, cx_osuo.exe accepts connections on any ports. This programme must be included in the firewall as a "secure programme".
  • Connections to the ObjectStore server are handled via port 51025, i.e. outgoing connections on port 51025/TCP must be allowed.

Procedure:
Under WinXP, the "Windows Firewall" is called up in the control panel. Exceptions must be permitted on the "General" page. Then select the Exceptions tab. The programme cx_osuo is added by selecting the button "Program" and specifying the path leading to cx_osr.exe under "Browse". By default, the file is located in the directory %CX_ROOTDIR%\Bin\. If necessary, ask the administrator. Confirm "OK" and the programme appears in the list.

  • Add the port 51031/TCP via the "Port" button. Simply assign a name, enter the port number, select "TCP" and confirm with "OK". Finally, confirm again in the "Windows Firewall" window with "OK". Now the connection to the ObjectStore server is again kept free of interference.
  • You must carry out the same steps for port 51025/TCP (from Windows Vista).

Windows 7

Call up "Windows Firewall" in the control panel

Call up advanced settings, click on "Incoming rules".

Click on new rule

Click on port, Next

Leave TCP, select specific local ports, enter 51025, 51031, Next.

Allow connection, Next

Deselect Public, Next

Enter ObjectStore_Ports as name, Finish

Server

  • ObjectStore accepts connections on port 51025/TCP and in turn establishes connections to port 51031/TCP on the client side.

Procedure:
According to the above client description, the ports on the server are to be enabled.
