How to Limit Access to File Server
If you want to enhance the security of your file server, you can regulate what hosts or networks will have access to your shared resources. Connections from other hosts will be refused by your file server. To manage access to your file server, open the Access tab.
On the Access tab, you can perform the following actions:
- View current access rules
- Add new hosts/networks that will have access to your file server
- Remove hosts/networks or edit their addresses
You can view all hosts and networks that have access to your file server in the table on the Access tab. If the list is empty, all hosts can access your file server. This is the default option.
To allow access to your server only from a specific range of hosts:
- On the Access tab, click the Add New Host/Network button.
- On the Add host page that opens, in the Network/Host address field, enter the IP address of the host you want to allow access (for example, 123.123.123.1) or the range of hosts (for example, network address/subnet mask written as 123.123.123.0/255.255.255.0).
- Click OK.
This will only allow the specified hosts to successfully connect to the shared resources on your file server. All connections from other hosts will be refused by the file server.
If you already have some hosts in the list and want to edit their addresses:
- Click the address of the host in the list of allowed hosts.
- You will be taken to the Edit host page on which you can edit the host IP address or subnet mask (for multiple hosts) in the Network/Host address field.
- Click OK to apply changes.
To remove an address from the list:
- Select the checkbox on the right corresponding to the host address you want to remove and click Remove all.
- On the next page, check the box to confirm removal of the selected hosts and click OK. To cancel the removal operation, click Cancel. If you remove all networks from the list, all hosts will be automatically allowed access to the file server.
