R5S - Using a 2.5Gbps port as the WAN port

Moderators: chensy, FATechsupport

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

eth0 1Gbps -> 1Gbps switch
eth1 2.5Gbps -> 2.5Gbps PC
eth2 2.5Gbps - > Internet


- WAN: eth2 (2.5 Gbps) -> Internet

- LAN1: eth0 (1 Gbps) -> 1 Gbps switch

- LAN2: eth1 (2.5 Gbps) -> 2.5 Gbps PC

This is an excellent way to take advantage of a future 2 Gbps internet connection without upgrading all your home networking equipment. By dedicating one of the 2.5 Gbps ports to your PC, you can ensure that at least one device can utilize the full bandwidth. The rest of the house will be limited to 1 Gbps, which is still very fast for most general-purpose use.

I have done your configuration before. It works but you should also pay attention to the Firewall Zone, set it to allow traffic from `lan` and `lan2` to access the `wan` zone, and your DHCP server is running on both `lan` and `lan2` interfaces to serve addresses in their respective subnets.

When your ISP upgrades to 2 Gbps, make sure the modem/ONT they provide also has at least a 2.5 Gbps Ethernet port. If your modem only has a 1 Gbps port, your maximum speed will still be around 940 Mbps, regardless of your R5S configuration.
