Anyone using a 2.5Gbps port as the WAN port on the R5S?
As from September, we'll have 2Gbps internet available. I'd be keen to know how to setup one 2.5Gbps port as the WAN port and the other 2.5Gbps port as a LAN port. I'd be interested to know the throughput too.
Edit: I manually edited /etc/config/network and swapped the WAN, eth0 (1Gbps) with the LAN, eth2 (2.5Gbps), so eth2 became the WAN port, and eth0 part of the br-lan. Did a reboot, it still all works, but a speed test from the internet is getting me 925Mbps - but that may be my ISP and not the router throughput or ports fault.
Edit2: I manually edited /etc/config/network, /etc/config/dhcp, and /etc/config/firewall. Now, the 1Gbps port connects to my 1Gbps switch (lan / 10.0.0.0/24), one 2.5Gbps port is my WAN port, and the second 2.5Gbps port is in a different subnet connected directly to my PC with a 2.5Gbps interface (lan2 / 10.0.1.0/24). So, if I get 2Gbps internet, my PC can take advantage of it even if the rest of the house can't. I've got qBittorrent running as a Docker container on the R5S.
eth0 1Gbps -> 1Gbps switch
eth1 2.5Gbps -> 2.5Gbps PC
eth2 2.5Gbps - > Internet
