I only know a little bit about networking so please ask if I’m not clear about anything.
My setup at home is VDSL > D-Link > Mikrotik.
I’ve learnt that everything is double natted.
D-Link on 192.168.1.0/24 provides wired local PCs and 5Ghz Wifi TV service so have to use D-Link.
Mikrotik (located some distance away) on 192.168.88.0/24 providing Local PCs and 2.4Ghz Wifi.
Printer on Mikrotik cant be seen from D-Link PCs as different subnet.
Anyway to get everything on one Subnet?
Currently I have WiFi for kids on Mikrotik with several Firewall rules I’d like to keep.
I was thinking that I could connect D-Link to LAN port on the Mikrotik and only use Mikrotik DHCP server?
More Detail below if needed:
VDSL Phone line > D-Link (Dynamic WAN DHCP)
D-Link IP 192.168.1.1
D-Link DHCP 192.168.1.1-254
D-Link Port 1 > Local PC 192.168.1.2
D-Link Port 2 > Local PC 192.168.1.3
D-Link Port 3 > Mikrotik WAN 192.168.1.4
Mikrotik WAN IP from D-Link 192.168.1.4
Mikrotik Bridge Ports 2-5 plus Wifi
Mikrotk DHCP on Bridge 192.168.88.2-254
Mikrotik Port 2 > Local PC 192.168.88.254
Mikrotik port 3 > Local PC 192.168.88.253
Mikrotik Wifi Printer on 192.168.88.252 (made static)
Indeed you could connect D-link to Mikrotik LAN side. You’d have to decide where you want to run DHCP server (and DNS server and…). D-link as vital device for internet connectivity is my first thought. And last one as well.
As you want to keep MT for filtering access from wifi devices, you’ll have to remove wifi device from bridge with ethernet devices. Before that you need to assign 192.168.1.x address to the bridge and remove 192.168.88.1. Reconnect to MT using the 192.168.1.x address.
After you break wifi device from the bridge, assign 192.168.88.1 address to it and start DHCP service on it. If you decide to use MT as DHCP server for 192.168.1.x, then you will have to configure another DHCP server running on bridge.
After you’re done, you can join ether1 interface to bridge … as you won’t be needing “WAN” interface on MT, you can make it a LAN interface.
Least troubles with getting wifi printer to be seen on 192.168.1.x … create virtual AP on MT and make it member of bridge (containing all ethernet interfaces). If you set IP statically on printer, then change it. If it’s served by DHCP (albeit configured as static lease), it’ll get one from DHCP server serving 192.168.1.x network. If you want “static” IP address for printer, assign static lease on 192.168.1.x DHCP server.
