Make lan traffic use only one wan

I am very new to openwrt so please bear with me!

I have setup an openwrt router on a GL.iNet GL-MT6000 with firmware OpenWrt 24.10.4 r28959-29397011cc / LuCI openwrt-24.10 branch 25.292.66247~75e41cb

I have Speedify setup on it to combine 2 x wan ports into one “conectify “ interface . I have my home network connected into lan5 and generally everything works well . My WiFi network is managed separately from openwrt using a UniFi network. I do have a few issues with Speedify as it’s a vpn and some apps don’t like this.

So I wanted to setup lan4 so any traffic going through this port only use a single wan port (wan1) , bypassing Speedify. I setup lan4 on its own separate vlan with its own dhcp server. And then I setup a firewall rule to point lan4 to wan1 hoping this would work.

It didn’t, and I must have missed something daft.

Grateful for any help,

Use Policy Based Routing to set the policies such that the network associated with port lan4 is routed through the standard wan instead of the VPN tunnel.

Thanks, i have now tried that. But for some reason i dont think it’s working.

Just to explain a little further. I have LAN5 port on its own subnet (192.168.10.0/24) , setup so anything that connects to this lan port uses the bonded connection (Conectify). This port is connected to WAN1 on the Unifi UDM SE. The Normal WIFI on the unifi network uses this WAN.

I then have setup LAN4 on the openwrt on a different subnet (192.168.11.0/24) which is connected to the WAN2 on the UDMSE, and i have a 2nd WiFi network that routes all traffic to WAN2 on the UDM SE.

I then have tried to do what you have said and used a PBR to route any traffic on the 192.168.11.0/24 subnet to just WAN1 on the openwrt router.

To test i have run speed tests on the UDMSE which shows the same external IP address for each WAN and the speed , which is way too high for WAN2, it must be still using the combined WAN for some reason. Very odd.
