Create route for LAN/WAN

Hi All,

I’m trying to use a LtAP Mini as a 4G modem connected to the WAN interface on my Cisco Meraki MX Router.
Obviously, it will give the Meraki a private (192.168.88.0/24) IP.
I’d like to be able to access the LtAP Mini from within our SD-WAN, which are all on the 10.0.0.0/8 subnet.
I suspect (I’m not a routing specialist, but know enough to be dangerous!) that I need to put a route into the LtAP to say that if I get any traffic from the 10.0.0.0/8 subnet, to send that back to the MX IP.
I can’t use the built in VPN function as I don’t get a publicly routable IP from my LTE modem!

Any ideas how best to configure this?

Hi,
In Mikrotik, in IP DHCP Server → Leases, make the address received by MX static.

Then
try adding a rule in the IP->Routes tab

DST. Address 10.0.0.0/8 Gateway:
IP address with DHCP for MX e.g. 192.168.88.100/24

and see if you can ping the MX address from the Mikrotik terminal, first to the DHCP address (88.x) and then to its 10.x address

Route in the ltap 10.0.0.0/8 via 192.168.88.1
Route into your SDWAN 192.168.88.1 via 10.YOUR.MERAKI.MX.IP
