Wan-Link Manager shows wan down, but in reality its up

Also, if i try to change the failover rule, it shows the following error: 'Gateway failover rule could not be updated'

Maybe there is an MTU size problem or a Speed negotiation problem with that interface and the fiber modems?

Thanks for the reply! However, I've been using these same modems with the same ISP for the past 1 year. This issue has suddenly popped up out of the blue.

Can you show us the non-functional interface definitions?

And the details, please?

OK, did you restart or unplug these modems from power recently?

Was there an update on the firewall system?

Why is one port on "Automatic" while the other is at "1000 Mbps - Full duplex"?

I would try setting MTU to 1300 bytes for one of these ports and then watch the reaction of that uplink.

If that helps, try the other port with that same setting.

No infra change recently. Nor was there any update. One modem has dhcp turned off, hence once is set to staic

Changing the MTU isn't working. Also, if i try to change the failover rule for the first WAN (Airtel one), it shows the following error: 'Gateway failover rule could not be updated'

What is the reason for that?

Hi,

please review each setting in the WAN manager settings in networks to see if the destinations are still active, after correcting any errors please try restarting the XG.
