Sometimes it’s necessary to provide access from outside to a workstation inside local network: for example, for an RDP connection to a local web-server. For such cases the port forwarding function exists.
To create a port forwarding, you need to specify the protocol, forwarded port (that will be opened on the server and to which connections from outside will be made) and also destination port and host (port and address of the workstation that needs to be accessed). If necessary, you can also specify interface, or a group of interfaces which will host this port forwarding.
Important: the IP-address of the host which should be accessed using port forwarding, should belong to an ICS CUBE user.
Also you can forward a port range, using the hyphen, like “10000-10100”.
Also, if you need local hosts to use the created port forwarding to connect to the destination host, you can turn on the “allow connections from local network” function. Attention! This way local connections will go through NAT and the destination host will treat such connections as if there would be initiated by ICS CUBE itself. If for the destination host ICS CUBE is not the default gateway, it’s recommended to turn on “Use NAT” option in the port forwarding.
For the allow rule for the forwarding port to be created automatically, you can fill the appropriate checkbox in port forwarding options. If you prefer to provide the access individually, you can add the rule manually. It should contain the destination port and the forwarding port divided by a comma in the “Destination port” field. The rest of the fields can be set according to your needs.
