Various tasks in timeSensor LEGAL need access to internet resources to run correctly. Therefore, you must enable certain ports on your firewall. Which ports these are depends on your usage scenario.
timeSensor LEGAL - Classic Installation
In the classic installation, the database server of timeSensor LEGAL is located within your law firm or within a virtualised environment. In this scenario, communication between client and server application does not need to be encrypted, as they are located within the same protected LAN. In this scenario, access from outside (e.g. home office) takes place via a VPN tunnel.
The following ports must be open on the law firm firewall in this scenario:
| Port | Protokoll | Initiierung | Beschreibung | |
| 80, 443, 8080 | HTTP, HTTPS | outgoing | Used to query the licence server so that new updates are recognised and displayed. | |
| 20, 21, 22 | FTP, SFTP | outgoing | Used to download updates via FTP. Note that large update packages up to 1 GB can be downloaded and the firewall must not block them. | |
| 465, 587, 993, 995 | TCP | outgoing | Only necessary when using the e-mail interface |
timeSensor LEGAL 365
With timeSensor LEGAL 365, the server is located in the data centre and the client communicates with the server via a TSL-encrypted connection.
On the server side, the following ports are open in this scenario:
| Port | Protokoll | Initiierung | Beschreibung | |
| 80, 443, 8080 | HTTP, HTTPS | outgoing | Used to query the licence server so that new updates are recognised and displayed. | |
| 20, 21, 22 | FTP, SFTP | outgoing | Used to download updates via FTP. Note that large update packages up to 1 GB can be downloaded and the firewall must not block them. | |
| 465, 587, 993, 995 | TCP | outgoing | Only necessary when using the e-mail interface | |
| 19812, 19813, 19814 | TCP | outgoing and incoming | Serves the encrypted data traffic between client and server |
On the client side, the following ports are open in this scenario:
| Port | Protokoll | Initiierung | Beschreibung |
| 465, 587, 993, 995 | TCP | outgoing | Only necessary when using the e-mail interface | |
| 19812, 19813, 19814 | TCP | outgoing | Serves the encrypted data traffic between client and server |
Broadcasting
The client application finds the server either by entering the IP address of the server once or - if the server and client are in the same subnet - by automatically broadcasting the server. Broadcasting means that the server continuously reports to the network via UDP protocol so that clients in the same subnet can see and display the server. Broadcasting is not always desired and is sometimes disturbing, for example if several servers are in the same network. The broadcasting of the server can be prevented by deactivating the UDP protocol on port 19813.
