Microtik Chateau LTE18 + Starlink + LTE

RouterOS Beginner Basics
1

Hi All,

i purcased a Chateau LTE18 running 7.12.1

I’m completly new to Microtik and with very basic programming capabilities.

  • I need to install a starlink antenna (without the original starlink router, the antenna is POE powered, i receive a clean ethernet from the antenna, so i also need to access the Starlink interface).
  • As the installation is mobile, I want that when i turn off the antenna the Microtik switches on the LTE internal sim for the connectivity.

So the idea is to connect the cable from the Starlink antenna to the eth1…but from here…PANIC!

I really don’t know where to start for the configuration

if i set in the address the ip address 192.168.100.1 that should be the one to access the dishy trough the app, internet goes down

if i let the microtik choose the addess:

Address 100.123.172.175/10
Network 100.64.0.0
Interface ether1-WAN

Everything works but no access trough the app.

Hi! Were you able to do it with success? I’d like to do the same in few days. I have a Mikrotik Chateau LTE12 and till now I’ve used only with LTE connection, I will use only with the ETH connection but I’d like to keep the LTE as a backup

HIgh level approach:

set WAN connection to ether1, use distance 1 or whatever
set WAN connection to LTE, use distance >“other connection”

And that’s it for most cases.

Default route with lowest distance will be used.
If that one fails, route for LTE becomes active and traffic can go over that route.
Once normal connection becomes available again, things will be moved again to route with lowest distance.

If I’m not mistaken.

LTE can be configured in the client dhcp on Eth2, for example, with a dynamic default route.

The LTE and the Mikrotik should not, it seems to me, have the same dhcp.

I don’t know if you’ve thought about it, but you need to configure the APN, PIN CODE, etc. properly.

I’m not pro Mikrotik but if I can help…

High level approache is not easy for me. I’m not able to do that now. I think that I must to restart everything with a factory reset. I cannot see the starlink lan in the defconf group and I’m not able to put that lan again into the group. I don’t know how was possible that I removed that one from the group.
