I am wondering, if there is a possibility to setup multiple DHCP Servers, or at least address ranges, to serve multiple VLANs, which are createable on the router, with IP addresses !? - I am not able to find an option for that…
Yes it is possible, and examples below are for setting up a Port Based VLAN, with its own DHCP Server …
First you will have to create the LAN Interface. Ensure you are logged into the GUI and are in Advanced mode. Go to NETWORK > LAN and click on the ‘Add’ button. In the example below, we create a new Lan Interface called ‘WuTangLAN’, and note that DHCPv4 is enabled. When you ‘Save & Apply’ it will have created the Lan Interface and the DHCP Server. For now, we are only going to setup the General Settings tab.
Now we need to assign the newly created interface for the VLAN to the Physical Settings of the Lan Interface for WuTangLAN. Go to NETWORK > LAN > LAN INTERFACE:WuTangLAN and assign its interface in the Physical Settings tab. In the drop-down interface list, select the newly created interface. In this example, you can see my newly created interface, from the previous step, is called eth0.11.
From this point onwards, you can assign the VLAN to an existing or new Firewall Zone, if required. The above examples are the basic minimum and any remaining configuration will be down to your individual use case.
I’m sure if you look on the Wiki, there will be helpful Teltonika examples.
