I have a Ubiquiti EdgeRouter Lite router which is installed with OpenWRT 22.03.2.
By default the eth1 interface corresponds to the WAN.
On eth0 I would like to create a "LAN2LAN" network with the network IP address 192.168.200.0.
On eth2 I would like to create a second network "LAN2WIFI" with network IP address 192.168.201.0.
This in order to separate, to segment, my wired network from the WIFI network.
Second question, my WIFI network printer must be able to print and scan on both networks; it is a BROTHER DCP-J752DW.
If I understand, you have to be able to open the following ports UDP 54925 Internal/External for network scanning and UDP 137 Internal/External for network printing and remote configuration.
Third question, are there ad blockers, like pi hole or adguard home, that could be installed directly in openwrt?
Fourth question, on the eth2 interface of the "LAN2WIFI" network, I am going to connect a Tenda Nova MW6 3 WIFI Mesh wifi system, in bridge mode or in static IP address, is it possible from openwrt to manage the home wifi and a guest wifi ( maybe from a captive portal, don't know)?
Thanks in advance for your answers and advice.
Philippe.
Based on your description, it sounds like you want to use eth0 for the wan, and eth1 and eth2 for the lan networks.... that's fine. these are easily assigned.
this is an invalid network... the range of each octet is 0-255. 300 is out of range.
I'm not sure what you mean by internal/external here -- unless you plan to forward those ports from the internet so you can print from the internet (external usually means "internet"; internal usually means your lan(s)).
Assuming that the priner uses standard IP to do this, and not mdns or other zero-configuration auto/discovery, this should be possible based on allowing the wired network to access the printer via the fireall (you can open the printer's IP address entirely, or just the specified ports).
AGH is available for OpenWrt.
It all depends on if your Tenda can support VLANs and multiple SSIDs (that device doesn't appear to be supported by OpenWrt, so it entirely depends on the vendor firmware). From the OpenWrt perspective, you can easily setup multiple networks and keep them firewall isolated. There are captive portals for OpenWrt, too.
You will not be able to manage the Tenda APs themselves from OpenWrt... but assuming bridge mode and VLANs are supported, you can administer the networks themselves (subnet, DHCP pool, firewalls, etc.) from your ER-Lite running OpenWrt.
