A company operates multiple departments across various buildings. Each building is equipped with a SMB router in the server room and a switch on every floor.
How can I do that?
For example, to restrict the actions of those specific users on the R&D department located on Floor#3 in Building#2, it is necessary to ensure that these R&D users can only access the internal network. For other users on the R&D department, there is no limitation.
Follow the steps below to configure the ACL rule on the SMB Router in the Building#2, here takes ER8411 as demostration:
1. Go to Preferences > IP Group > IP address on the router. Click +Add to add a new IP address entry.
Specify the IP Address Range as 192.168.0.32-192.168.0.63 for the specific R&D department users, click OK.
Then specify the IP address range for all internal network.
2. Set IP Group for corresponding IP address on IP Group. By default, there is an entry “IPGROUP_ANY” covering all IPs, and cannot be edited.
3. Go to Firewall > Access Control, click +Add set up the rules as below.
The router processes rules sequentially for each packet. In the Access Control List, the rule with a smaller ID has higher priority. Since the router evaluates rules starting from the highest priority, ensure that the Allow rule have the smaller ID number than the Block rule.
4. Verification
After configuration, these R&D department users cannot access the public IP at any time.
All departments are in the same network, and limit the acts of the R&D department users.
How can I do that?
For example, to limit the acts of the R&D department users, it is required that the R&D users have no access to the internet. For other departments, there is no limitation.
Follow the steps below to configure it, here takes ER8411 as demostration:
1. Go to Settings > Profiles > Groups. By default, there is an entry covering all IPs, and it is not editable. Click +Create New Group to add a new group entry.
2. Specify the name of the IP group as “R&D”, and select IP Group as the type.
Specify the IP subnet as 192.168.0.32/27. IP subnet represents the range of IP addresses you want. In this example, 192.168.0.32 means the IP address and /27 means the number of bits in the mask. Click Apply.
3. Go to Settings > Network Security > ACL. Under the Gateway ACL tab, click +Create New Rule.
Specify the name as “Deny R&D”, check Enable on status. Select Direction as LAN -> WAN, the rule policy as Deny, Protocol as All, “R&D” as the source IP group, “IPGROUP_ANY” as the destination IP group. Keep the advanced settings section as default, click Create.
4. Verification
After configuration, these R&D department users cannot access the public IP at any time.
The article demonstrates how to restrict employees to accessing websites exclusively via HTTP on the internet at any time.
How can I do that?
Follow the steps below to configure it, here takes ER8411 as demostration:
1. Go to Firewall > Access Control on the router. Set up the following three entries as shown.
1) Allow HTTP service for all the Source and Destination.
2) Allow DNS service because DNS service always works together with HTTP service.
3) By default, all services are allowed in the Access Rules. In order to block other services, block All Services in the last.
The router processes rules sequentially for each packet. In the Access Control List, the rule with a smaller ID has higher priority. Since the router evaluates rules starting from the highest priority, ensure that the Allow rule have the smaller ID number than the Block rule.
2. Verification
After configuration, the employees cannot access the Internet via https.

A company has two departments: R&D department and marketing department, and they are in different subnets. The R&D department has access to computers in all VLANs for data backup, while computers in the marketing department are restricted from accessing the R&D department VLAN to enhance data security.
How can I do that?
Follow the steps below to configure it, here takes ER8411 as demostration:
1. Go to Network > LAN on the router, click +Add to create a new network, and fill in the configuration according to the network requirement. Set the IP address/subnet mask as 192.168.10.1/255.255.255.0, mode as Normal assign VLAN 10 to the network, and enable the DHCP server.
After saving, the network settings on the router as below.
2. Go to Network > VLAN to change the VLAN settings.
Normally, after creating a new network, all LAN ports of the router will remain UNTAG in the default network and will be automatically added to the TAG VLAN of the new network.
Based on the network topology: an unmanaged switch is used to extend more Ethernet ports, change the Marketing LAN port (Port 4) to UNTAG VLAN 10 and set the PVID to VLAN 10, R&D LAN port 5 to UNTAG VLAN 30 and set the PVID to VLAN 30 respectively.
3. Go to Firewall > Access Control, and click +Add button to create rule as below. Note that the "LAN -> LAN" interface signifies an inter-network traffic ACL entry. This rule prevents the marketing department from accessing the R&D department.
Note: Stateful ACL requires the supported firmware of the router.
Note: We recommend keeping the states type as default setting. If you select it manually, please refer to the following picture.
New: Match the connections of the initial state. For example, a SYN packet arrives in a TCP connection, or the router only receives traffic in one direction.
Established: Match the connections that have been established. In other words, the firewall has seen the bidirectional communication of this connection.
Invalid: Match the connections that do not behave as expected.
Related: Match the associated sub-connections of a main connection, such as a connection to a FTP data channel.
