Internet and LAN Extender

ShaunFavell · January 19, 2024, 9:40pm

Hi - I’m pretty new to Mikrotik, and spent quite a lot of time playing and researching this week. I’ve learned some stuff, but am stuck on a few bits.

The plan is to receive the wifi broadcast from my Starlink router with my MT C53UiG+5HPaxD2HPaxD ax3 device. I then wanted other devices connected to the MT by ethernet (my homelab servers) to be seen on the Starlink LAN via wifi so I can access them locally. I also want those devices to have access to the internet.

At the moment I have got the setup so the MT device connects to my Starlink via wifi, however, the devices on the MT LAN Bridge cant see the internet, though I can ping google.com from the MT terminal.

I’m using the GUI more than the CLI. What am I missing?

I’ve run into a dead end so tried a different approach.
I set up the MT in default settings to give a default wifi signal to connect to my router.
In this configuration the internet would come into the WAN eth1 connection.
I set the second wifi radio wifi2 to station and connected it to my existing starlink wifi to get internet access SSID=“FatParamotorHQ”. I added this device to the WAN list.

When I connect my laptop to the MT wifi (wifi1) SSID=“Homelab” I get a similar problem - it sees no internet. The devices connected to the MT router by ethernet see no internet.

In the MT terminal I can ping google with no problems.

How can I configure the NT so the ethernet ports and the wifi1 can see the internet coming via wifi2?

Many thanks … Shaun

I seem like not seeing any route?

What is the output of
/ip route print
?

Using your second config

From memory, the starlink will be handing out 192.168.1.x IP addresses, so without some fiddling
you can’t have a 192.168.1.x address on the Mikrotik’s bridge, for this mode of operation.

add address=192.168.1.131 comment=defconf interface=bridge network=
192.168.1.0

Indicates a /32 network.
(Except change .1.x to most anything else I am going to use .2.x)

You will want something like

add address=192.168.2.131/24 comment=defconf interface=bridge network=
192.168.2.0

Then in the dhcp network section and pool, you should change the settings to point at the mikrotik bridge

/ip dhcp-server network
add address=192.168.2.0/24 dns-none=yes gateway=192.168.2.131

and similarly with the pool.

One other option, (that with luck might work)

They have implemented very recently station pseudo bridge for the new wifi,
This may allow you to bridge from the mikrotik to the starlink.
(In which case you can have a .1.x ip address on the bridge, but dhcp is sent from the starlink)
Turn off rstp on the mikrotik bridge, it seems to cause issues in this mode.
