Is Balance 30 LTE good if my internet connection is 300 Mbps

My internet connection is 300 Mbps. I don’t plan to use any firewall on the balance 30 LTE router.

I see that this router has a 200Mbps “stateful-firewall throughput”. Will this cause a problem?

Thanks.

Yes if you want to use 300MBps, no if 200MBps is enough bandwidth.
