    Exclamation WAN Link failover problem with routing policy on TL-ER5120 V3

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    Hello,
    I’m trying to get my new router up and running for my home office.
    I have a network with a Lan accessing the TL-ER5120 v3.0 (192.168.1.0/24 on LAN port) router through a layer 2 switch. Router is connected to Internet with WAN 1(192.168.0.2) connected to an ADSL modem (192.168.0.1) and WAN 2(192.168.8.2) connected to 4G Huawei router (192.168.8.1).
    I am using DHCP on the router for the LAN and some for some “VIP” PC’s I use Address Reservation.
    I have 2 different groups of computers, VIP (Group 1) and others (Group 2). I created those two groups in the preference menu of the rooter.
    I would like to take advantage of WAN1 and WAN2 using load balancing for VIP group web surfing (HTTP and HTTPS) and force all other services of this VIP group (SMTP, IMAP, POP, FTP and so on) on WAN 1.
    Group 2 must go on the Internet using WAN1 for all services.
    In case one the WAN Link fails all traffic has to be redirected on the available link until both link are available.
    I am using policy routing with:
    Rule 1: Group 2/ all services go on WAN1
    Rule 2: Group 1 / FTP service on WAN 1
    Rule 3: Group 1 / SMTP service on WAN 1
    Rule 4: Group 1 / POP3 service on WAN 1
    Rule 5: Group 1 / IMAP service on WAN 1
    Up to Rule 9 Group 1 for other common services on WAN1
    Ideally, I would have liked to do for Group 1: all services but HTTP an HTTPS go on WAN1. To avoid services unset in the list to go WAN2. But I don’t know how to do this because of rule ID priority.
    Anyway, all this is working fine for most common services used by Group 1. The problem is that if WAN1 fails, Group 2 and Group 1 for all specific services set in the routing policy table cannot go on the Internet. However, I can see that WAN1 is offline.
    I did not enable Link backup because I need to use both WAN links for Group 1 web surfing.
    When I read the TPlink specs it is supposed to be working since “Link always on” functionality overrides theoretically Routing policy.
    Any help will be very much appreciated.

    When WAN1 fails, you mean the policy routing you configure could get access to Internet via WAN2 or not? I need confirm..If it could get online, it is normal.

    No actually, I mean than the policy routing remains the fist priority, and all devices set to use WAN 1 don't switch to WAN 2 and have no service to the internet.

    Bro, I have some TL-ER5120 v3. Never heard of this. Could you post some configuration screenshots of policy routing?
