Implement VLANs for Networks at school

Peace be upon you, and Allah mercy and blessings.
In this tutorial we will provide a VLAN Implementation for Network tutorial at school, let's do it together according to the topology above ...

For Router 1, our first step is setting the Gateway Server by clicking the link below

If you have reached the last stage, the next step is to bridge ether 2-5

After creating the bridge then we create a VLAN for Router2 - Router7. VLAN ID is adjusted to the topology above and all interfaces are the same, namely ether 2.

Next we create an IP Address for each "VLAN, for Router 2 IP Address 192.168.2.1/30 Interface vlan-R2, and on Router 3-7 the IP Address is filled with the Gateway Server in each" VLAN according to the topology above

The settings on Router 1 have finished, then we set Router 2-7 with the following steps ...

On Router 2 we first create the VLAN with VLAN ID according to Router 1, Interface ether1

On Router 3-7 settings it is also the same as Router 2, only VLAN IDs that we have different settings / follow the topology above

after creating a VLAN on Router2, then we create an IP Address with IP 192.168.2.2/30 Interface vlan1-INET

For Router 3-7 the IP Address is adjusted to the Gateway Server as in Router 2

If the laptop you are using wants to connect to the internet then we set the local setting to ether 2 with the IP address as shown below.

Next we create DNS, namely 8.8.8.8 and 8.8.4.4 as shown below.

In order for us to get internet access on router 2 in the NAT settings we change Chain to look, Out Interface vlan1-INET and Action we change to Masquarade, as shown below.

Next we are NAT Settings again to access the internet on the Laptop with Chain: Scan, Dst Address 0.0.0.0, Protocol: 6 (tcp), Dst.Port: 8080, In interface: eher 2 and on the Action menu, change the Action to redirect and To Port 3128 as shown below.
