Hello, my friends,
I want to use the OpenWRT system on a Mikrotik RB750gr3 device in order to combine three Starlink connections. Does this system provide better results than Mikrotik’s own system? Are there any problems or drawbacks?
Please help and guide me to the best option. Thank you in advance.
The SoC is not sufficient for 3x 250Mbps. It can forward at 300-500Mbps without offloads or 2Gbps with them. Offloads exclude multi-wan(use different uplink for different traffic), do not apply to mptcp (aggregate all links using cloud server)
Mikrotik may or may not be better at selective offloading potentially offering a bit better throughput, but i am not holding my breath.
All LAN ports are connected to one gigabit port to SoC CPU and WAN port to another, so you need to put all starlinks to LAN ports and hope aggregated "internet" comes out of WAN port.
Any filogic router (and certainly x86 mini-pc) like banan-pi (more of a kit board with many ports) or flint2 (full router with wifi) will have 2x2.5Gbit internal ports and 50x faster CPU for all your forwarding/encapsulating needs.
Unless you get it dirty cheap, it's probably overpriced too.
