23.1 Legacy Series / Re: Intermitten Internet Connectivity Issue
« on: April 12, 2023, 07:29:00 pm »
1. GWs are monitored through monitor IPs, Google DNS on WAN1, Cloudfare DNS on WAN2. Trigger conditon is high latency or packet loss. WAN1 is the one which shows slight packet loss every once in a while (albeit under the threshold defined) but stays 'online'.
2. Okay, my original issue is that clients loose internet connectivity inntermittently. I'll stick to the same. But the fact also remains that DNS behaviour is the way I described. What that meant was that while the Firewall is able to not only ping the DNS servers, but even resolve quesries for its own traffic, the randomly affected clients are able to do neither at that time. If it makes life easier, we can ignore that.
3. I've had this ISP for years along with pfSense. My issue at hand has surfaced only post my migration to OPNsense. It could very well be conicidental yes, but I was observing this issue for a good deal of 3 - 4 days untill I finally switched to a Failover Group which immediately solved this issue. It might very well not be coincedental as well. I'd be interested to know what tests / exercisises / logs could I dig into to be sure.
Thanks & Regards,
