To only allow connections to the Sales network that originate from the Internal network, you can set up firewall rules on the network devices or use access control lists (ACLs) to enforce this restriction. Here's how you can achieve this:
1. Identify the IP range or subnet of the Internal network and the Sales network. For example, assume the IP range for the Internal network is 192.168.1.0/24 and the IP range for the Sales network is 10.0.0.0/24.
2. Access the network device (e.g., router, firewall) that connects the Internal network to the Sales network.
3. Configure an inbound firewall rule or ACL on the device to allow incoming traffic to the Sales network only if it originates from the Internal network.
4. Depending on the device and its configuration interface, use the following steps as a general guideline:
a. Access the device's management interface, such as a web-based GUI or command-line interface.
b. Navigate to the firewall or ACL configuration section.
c. Create a new rule or ACL entry.
d. Specify the source IP range or subnet as the Internal network (e.g., 192.168.1.0/24) and the destination IP range or subnet as the Sales network (e.g., 10.0.0.0/24).
e. Set the action to allow or permit.
f. Apply the rule or ACL entry.
5. Ensure that this rule or ACL is placed before any rules allowing access to the Sales network from other networks in the device's rule or ACL order.
6. Save the configuration changes and test the setup by trying to access the Sales network from a device in the Internal network. The connection should be allowed, while connections originating from outside the Internal network should be blocked.
Note: The steps described above are general guidelines and may vary depending on the specific network device and its configuration interface. It's advisable to consult the device's documentation or seek assistance from a network administrator if needed.
Only allow connections to Sales network that originate from the Internal network.
