Hello,
I have an Asus RT AC66U, running the Merlin firmware (though I haven't had chance to check yet if the problem occurs with the stock firmware as well).
My problem is that I have poor throughput when accessing a service via port forwarding, and the router CPU goes to 100%. I have a gigabit internet connection and can easily achieve 800mbit up and down on a speedtest, but if I host a speedtest myself (librespeed) and try to access it externally, through port forwarding, I'm maxing out around 100-120mbit.
I have tried internally on my LAN as well. If I access the local speed test via a private IP (192.168.1.x) I get full gigabit speeds. If I access via my external IP, which still only goes to the router but then I presume goes through iptables rules and redirects internally according to port forwarding rules, I'm again limited to 100-120mbit and CPU usage is maxed out on the router.
Is this a limitation of how port forwarding works on this router? Potentially an impact of some Merlin feature? I will try to do a hardware reset, and try flashing with stock firmware and retesting when time and work permits.
Thanks in advance
