So I have the L009UiGS-2HaxD-IN on which, at some point, I moved WAN to the Eth8 due to be able to powerup ONU through the PoE (which is failed btw ). A couple days ago I found a schema for the L009 which mentions direct connection of the Eth1 to the CPU (I would guess it is for the PoE-in purpose) and the other Eth2-8 through the switch-chip.
Current setup: Firewall config is pretty much simple, default from MT, DHCP client, DHCP server and the NTP client. Also going to try the Adlist feature from the DNS with DoH
So the my question is: Does it have some performance benefits of any kind to have the WAN on the Eth1 in comparison to other Eht's?
Similar problem with Hex Refresh, Hex S 2025, ...
The fact eth1 is not part of switch chip, means it can not be HW offloaded.
For pure router function it will probably not give such an impact but if e.g. you want to put all 8 ether ports in 1 bridge (switch setup), you need to keep in mind ether1 will ALWAYS pass CPU since it's not part of switch chip. And then performance can be impacted.
HW offloaded ether2-ether7 will reach wirespeed without problems in such a setup but ether1 will most likely not.
It's should better now as all traffic does not flow unconditionally through CPU if not needed.
It doeas not meen that you will notice MUCH better throughput/saturation as CPU could have been handling it with no sweat all the time.
If using as home router/switch, it's best to use ether1 for WAN because it can not be HW offloaded.
And then rest of your ether (and SFP) ports can be used in normal switch config.
But that's just optimization. At the end you can configure it the way you want just keep in mind there may be consequences performance-wise.
