LTE, no connection, missing route?

RouterOS General
1

that you everyone for earlier support, however, i just got a new device with LTE built in. Everything seems to work fine, i can ping and trace-route from mikrotik, but not traffic to LAN or DHCP-server clients. I’m still learning, thus hoped someone can point me to what I’m missing. Here is the present config.

System is not showing routing table, so here it is manually:

I get a feeling that i’m missing a route…

I have not used LTE routers but have a feeling this should be your problem

/ip dhcp-client
add comment=defconf dhcp-options=hostname,clientid disabled=no interface=ether1

change interface to your LTE interface and enable add default route.

give it a try

cant make those changes… the specs are locked after setting it up through LTE interface.

I had simular issue when the router was getting traffic and resolving DNS but clients wouldn’t in L2TP/IPSEC situation, Sindy was able to guide me and explain.

Now, I’m experiencing similar symptoms but now with LTE.

cannot have a dhcp-client on LTE interface?
well, you can still set up static route for outboud traffic

add dst-address=0.0.0.0/0 gateway=gateway of LTE connection (or just the LTE interface)

Edit: just checked your config again, this route is already added, not sure why now.c Maybe change the gateway=:LTE to the gateway IP of LTE connection ?

Ip routes, are all static. “DAC”

The problem is that similar symptoms may not have the same root cause.

I haven’t really understood from your initial post what is working and what is not, but I can see that you tell your DHCP clients to use your Mikrotik as a default gateway but you don’t tell them what DNS server to use:

/ip dhcp-server network
add address=192.168.88.0/24 comment=defconf gateway=192.168.88.1

So you should use the following command:

/ip dhcp-server network set [find address="192.168.88.0/24"] dns-server=192.168.88.1

(as your dns settings say you permit yourself as a DNS server for others).

Sindy, your competence is impeccable. thank you very much
