I am trying to set up dual WAN for failover on GL-MT6000.
I have a router configured in bridge mode that I am trying to use for failover. Everything appears to be working in bridge mode. When I plug it in ethernet port of my laptop I get internet connectivity and the public IP of my provider is assigned.
I configured Ethernet 2 port of GL-MT6000 as WAN but when I plug my router I don't get internet connectivity. Ethernet 2 displays message " The interface is connected, but the Internet can't be accessed. ". IP address shown on this page is not a public IP of my provider but local IP address in the range 10.x.x.x.
What am I doing wrong? Any ideas how I can get it to work?
Primary router/ ISP modem -> MT6000 --- 10.x.x.x
Primary router/ ISP modem -> Laptop --- Public IP
I tried to understand your network topology.
There should be a Primary router/ISP modem.
When connecting the MT6000 to it, the WAN port only displays 10.x.x.x.x, when the laptop connects it, it will directly obtain the ISP public IP without any configuration (with DHCP, without PPPoE)?
If I did not misunderstand this, you want to obtain the ISP public IP on laptop or any device including the router, it supposed to be need PPPoE/PAP and other authentication to obtain public IP.
Please consult your ISP, how to configure if connect a router
So wan 1 did work as expected correct?
If wan 2 fails then recheck configuration. Start with cold boot then boot to config to see that it is indeed the wan2. Guess you could ssh to command line to see state or use luci for more clues.
Primary router/ISP modem is on WAN1. That's working without any problems. As I mentioned in my original post, I am now trying to set up a failover using WAN2 and a different ISP provider/modem. So the config looks like this:
The device I am using for WAN2 is a Huawei B628-265 4G/LTE router. It's configured in Bridge Mode and it does connect to ISP and obtains public IP. This is confirmed by the led lights on the device and this is what I also tested by plugging my laptop directly into the router. I get internet connectivity on the laptop when I do that.
Interesting thing is that when I disconnected primary modem from WAN1 it does seem to failover to secondary ISP and I get internet connectivity.
What I am trying to understand/correct is the errors when WAN2 is on standby.
Thank you for your clarification, it is very clear now.
It turns out that the primary router of WAN2 is a modem and is in bridge mode, that is reason why it did not require to PPPoE/PAP to get the public IP. lol
When there is a problem with WAN1 (ISP modem), switch to WAN2 (backup link, Huawei modem), is the second link also available?
However, WAN2 still can't get the public IP?
It's a bit strange. If a laptop can obtain a public network IP from Huawei, then the WAN2 of Flint 2 should be available.
There should be a problem with the Huawei modem offer IP, maybe it judges that the client (Flint 2) does not meet certain requirements, so it will offer a private network IP.
You can try to clone the MAC address of the laptop to WAN2 of Flint 2.
Please restart Huawei Modem to let it re-offer IP to.
