Problem with WAN disconnecting intermittently (Cable modem for WAN and Tmobile Home Gateway for OPT)
-
My setup is a Netgate 1100 with the WAN port hooked up to my Spectrum Modem and the OPT port is connected to my T-mobile WiFi Gateway (which I cannot turn off the routing feature on, unfortunately) and the LAN is connected to my Eero router in bridge mode for WiFi throughout my house.
I set up a failover gateway group with Tier 1 being my Spectrum WAN and Tier 2 being my Tmobile OPT so that when spectrum goes down, the Tmobile kicks in and that's been working so far. But the problem lately is the WAN intermittently kicks me off despite the spectrum modem working fine with the lights showing that I'm online. The monitoring gateway IPs are google DNS servers 8.8.8.8 and 8.8.4.4 for WAN and OPT respectively. Could this be a problem with the DNS servers acting as gateway monitoring or could this be an issue with the DHCP assignment from the Tmobile Home Gateway router? Thanks in advance.

A light ... wouldn't help much if a connection is stalled for several milliseconds.
Ordinary (ping) packets send out from pfSense to, for example 8.8.8.8 and don't come back, that's an issue.Btw : always keep in mind : the day 8.8.8.8 or 8.8.4.4 or 1.1.1.1 decide that their main job is "DNS for the people" and not replying to ping, so they shut that down, millions of routers that ping these guys to check if they are online (== "online" actually si more : "can they reach the (DNS) servers with a ping?" not more, not less) will go off line, although their connection to the net is just fine.
That's why it is probably 'better' to locate a close-by ISP router to ping to, not the one @home, but a bit further upstream, and have that device pinged.
You can find them with, for example, tracert.You use a spectrum modem : throw that spectrum word into the search button (above) on this forum. You'll find references.

@Gertjan thanks for that reply, I went ahead and just left the gateway monitoring IP field blank and it defaults to the ISP gateway but the problem keeps happening. I didn’t have this problem when I had the Starlink in passthrough mode connected to the OPT. Now with the T-Mobile gateway, I can’t put it into passthrough mode so could this be an issue because of that configuration? How can I change the pfSense settings to accommodate for the fact that the T-Mobile gateway can’t be passthrough?
