[Multi-WAN] One gateway goes down at random times without being actually down…
-
What does your line quality graphs look like? If you have high enough pings, you might need to adjust the gateway monitoring settings for a slow or or slightly poorer quality line.
-
I've had the same issue ever since I upgraded to 2.0.2.
-
@podilarius:
The line quality seems fine - at times, when there is a line fault upstream it is worse. But, then the failover works and reconnects when the line quality improves again.The problem I'm having is that at seemingly random times the line is reported to be down, when it is really not - regardless of the line quality.
The real problem being that it stays down indefinitely. Changing to another default gateway and back to the original default gateway fixes it instantly.
Any ideas?
@TwigsUSAN:
I have had this issue since 2.0.1 -
Try turning on "Allow default gateway switching" option under "System/Advanced/Miscellaneous" menu.
It should keep you online if your default gateway goes down and until you can diagnose what the problem is more in depth.
-
Yes thanks - my "Allow default gateway switching" is already turned on.
Any ideas where to start diagnose this issue?
-
My system logs only display the following message:
php: : MONITOR: WANGW is down, removing from routing group
And, then that particular gateway is down indefinitely, until I change the default gateway and back again. This is very inconvenient.
-
Are there any other errors apart from that? are you running dhcp or static on your wan? sorry if you've already mentioned it, also check to see if you default wan drops at a particular time
-
No errors except this one.
All my WANs are static. Funny enough the default WAN doesnt drop, but the others do.

I use only Intel PRO/1000 GT NICs.
you use the Intel Kernel modifications ?

(they can also be set in System => Advanced => System Tuneables)This post can help you perhaps also - there was an solution with 2.0.2 Problems with Intel NIC:

Thanks for the suggestions.
Any ideas on how to debug this? Is there somewhere where I could find some more detailed logs?
-
Hello,
I have the same problem, no solution on sight.
All my gateways (5) are marked down a the same time, and goes all up around 10 secs later.
-
I finally find out what I was doing wrong. All my virtual interfaces where NOT mac-spoffed. So all interfaces had the same MAC address. In that way, the MAC table of the switch was going crazy .. the same mac address can NOT be on different port at the same time.
Shame on me -(
