Model : TL-ER5120Hardware Version : v3Firmware Version : 3.0.2 Build 20180125 Rel.35267ISP :I have 3 WANs connected on the router. First one is the main, used for everything (internet, db, ftp, etc). I'm testing one ISP in my WAN2 as a Failover and it is working fine. I don't wanna use the WAN3 for internet. I just wanna use WAN3 in a specific port in one virtual server. The problem is that when WAN1 fail and I'm not using WAN2 (ie disconnected), the router assumes the WAN3 (like a failover).I don't have any Failover configuration about WAN3 and my policy routes is only WAN1 and WAN2.What should I do about it?
