WAN Backup configuration for lte5388-m804

romanomauro

Hi, I am trying to configure this LTE router to have a backup connection to an ASUS DSL-N55U.

Unfortunately I can't get it to work, does anyone have a guide or experience to share on this?

What I did:

1) Enabled WAN on LAN1 port

2) Network cable from Zyxel (WAN) to Asus (LAN)

2) Set IP 192.168.2.1/255.255.255.0 on ethernet interface in Zyxel

3) tried to disable all firewalls.

Asus is connected to the internet via WAN / USB / LTE and exits on the internet via Zyxel. But when Zyxel loses the connection it doesn't pass the command to Asus.

I have dealt with multiple ways but I don't find the right one.

Thank you,
Mauro

Hi Mauro, 

Does the ASUS DSL-N55U have a fail-over/fall-back design?
I think it should determine which WAN interface has connection and which does not so that fail-over/fall-back between the main interface and the back-up interface (e.g. Zyxel LTE5398) can happen. 

Regards,
