@mhweb said in Netgate firewall ISP gateway is offline and has packet loss, how to fix it?:
The problem I'm facing is that I'm getting 100% packet loss in the WAN interface; therefore, the internet connection drops.
When you power up two switches, with no cables what so ever, all the port LEDS will be out on all ports on both switches.
You can actually se that their is no connection now where.
Now, hook up a network cable on one switch to the other switch.
Both ports on both switches slight up : at this moment a connection exists. A steady, but empty -no real data - carrier is maintained between these two switches.
Now you have created a typical situation that can also exist on your pfSense WAN port. The connection is UP, port LEDS are on, indicating the carrier speed) but nothing flows over it.
How does pfSense knows that the connection actually works ?
Simple, it sends every half a second :
0b5249e5-4371-4d52-9e4a-7c2606d34932-image.png
a ping.
And if the reply comes back, the time is used to show this info :

And here it comes : what if the IP where pfSense pings to decides to stop answering to these pings ?
The "Internet" connection is still just fine, only this one and only IP stops answering you.
The reaction of pfSense will be, eventually, that it decided that the connection is 'bad' and it will reset the interface.
By default, the first upstream gateway device is chosen as a ping destination, but you can also chose another one yourself :

or you can decide not to monitor at all. After all, if your ISP is any good, why would it fail ? 😊

and problem solved.
If, when not monitoring, the connection still doesn't seem to work : the problem is also solved.
Do your ISP shopping elsewhere. You are the customer, you decide. Many customers will make, or break, an ISP.

I called Verison for them to update the settings to use DHCP for WAN port, and they didn't even know what a router is.
That like buying a new car at the local BMW dealer, and you ask : what type tires does my new car has ? They say " tires " ?
Normally, in such a situation, get your money back, don't argue, don't say word, keep being friendly, and go some where else asap.
