Multi-WAN Issue with one Link always
-
Did you check the RRD graphs and why the link went down ? Is it packet loss or high latency ? You can increase these values on each gateway.
Sure that your modem isn't disconnecting after some idle time ?
Can you try with your modem as monitor IP ?

Thanks for reply
Yep i tried all that . and modem didn't went idle or down and yes i monitor with PRTG to check the modem connectivity ( another machine connected to another port on the modem ) . and the latency some times reach high percent but i am not using it , i am using to check the member down only … anyway NOW i am putting the monitor IP is the modem LAN interface ! and this must be Online all the time ... ( just for testing ) i will update here .. -

That would be the next thing to check if it is pfsense or something else.

well , it seems to be something related to the RTT , and latency for sure , after i change the monitor IP to internal modem IP , it didn't go offline for 2 days with heavy load over the line . the RTT is less than 1ms off course . so i think it is related to hight latency when i put the monitor IP as ISP outside IP ( or google DNS or any other IP outside )
according to RRD Graph Quality it reached 800-1000ms for the ADSL line . so i think i can put the Latency thresholds to be between 1500m and 2000m and change the Trigger Level to high latencyWhat do you think?
-
With latency that high, you probably have some kind of problem unless you have a satellite connection. That's generally indicative of a problem. Maybe pick a closer monitor IP if you're using something that's on the other side of the planet. Otherwise, yeah just increasing the latency thresholds will work.

yes right . i changed the IP to another IP which sometimes stuck in gathering data , i am kinda sure it is related to RTT . any i will test some stuff and i will update here , to see if this will be closed due to ADSL high latency issue .
Thanks

Ok this topic can be closed . seems to be nothing related to pfsense ;)
-
OK a minor update
i think it is something related to my link and also pfsense .
see when the link is offline ( red in the main portal ) and i know it is not . i just go to routing/adsl route interface and just press save changes ( without changing any thing ) same IPs , same monitor IP and every thing . then when i press apply changes , the interface come online
my fix would be make a cron job to check the interface every 10 mins
so what do you think ?
my idea is something related to ifstat may be ? -
just to confirm this . i thinf pfsense didnot recheck the GWs if it goes offline.
i face this again in another site with same design , and now one link of them is Gathering data , and the link didnot is working fine. but had some hight RTT is some period of time . -
The gateways are constantly checked whether online or not, and are brought back online as soon as they're up and functioning again.
