General • Re: Mikrotik Chateau AX (5G) eth1 + lte1 load balancer with failover - looking for a tutorial

You mention load balance & failover. Do you mean: if BOTH "ether1" ("dorm server with DHCP") and "lte1" have working internet, split the traffic between them & if one fails all internet traffic goes out the one working one? Or do you want it always using ether1 if it's working, and only use LTE if ether1 is down?

Also, do you have LTE already setup? e.g. if you unplug ether1, does the Chateau work via the LTE? If so, do a speediest (or several) to get a sense of the LTE speed. Then plugin ether1, and do same speed test with "dorm-server internet". e.g. If you want to load balance, it's helpful to know the relative performance of two internet (dhcp and lte), to know HOW to "balance" them.

Really good questions, thanks!
- Yes, both (eth1 and lte1) have working internet
- Yes, LTE is set up and working the speed is around 70 mbps at day and 200 mbps at night (depends of the usage of the cell towers)
- Yes, eth1 is connected to the dorm-internet-server and needs a DHCP-client to work to retrieve an IP from the dorm-internet-server. The speed is around 25 mbps at day and 80 mbps at night.

- Yes, I want to split the internet traffic between them
- Yes, if one fails, all internet traffic should be forwarded to the working port
- No, at this point I don't know how to balance them and what's important to know. Also it would be helpful to know the setup of the firewall against security breaches.

So it would appear ether1, is a fixed private IP you get from an upstream router?
The LTE would appear to be possibly a public IP that is dynamic (can change)??

- Yes, eth1 gets a fixed private ID from the dorm-internet-server (router)
- I don't know if the lte1 public ip is dynamic and can change.

Question:
I want to achieve that the lte1 intereface is "selectabel" in the device list and gets a fixed IP. As workaround: Would it work if I create a virtual ethernet interface (virteth1) with a fixed IP and forward the lte1 traffic though the virtual ethernet? Afterwards setup load balancing between eth1 and virteth1...
