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.

Still not working 

Please check each address you are using to test, try using the ip address of each interface as the fail test network. Please post a copy of the wan link manager settings.

Tried changing the Ip, but am getting the following error: 'Gateway failover rule could not be updated'

Please post a copy of your wan link configuration.

When i try to add another condition, I get the following error:

what device has 254 has its address? I asked you to change it to the WAN interface address which is 1.15.

Ian

Its the isp router. 1.15 is the ip of my nic

So you have an ISP router in front of your XG on this interface. Has the ISP performed a firmware/reset upgrade on the router which is blocking the ICMP traffic from your firewall?

Ian

No, no update to the ISP router. If i directly connect to the Router via my mobile/other laptop via lan to check the connection the internet is working fine.

Also, i would mainly want to know why its not allowing me tk change the IP in the WAN link manager. Is there some config inconsistency at the backend?
