Gateway offline, Packetloss
-
@stephenw10 IP is showing permanent with the gateway incomplete, What does that mean ?
-
@apaar I'm curious, if you reboot pfSense, does it then come up or does it stay down?
-
@robh-0 The link is up but the gateway is down.
-
@apaar I understand. Mine started doing the same thing recently. If I disconnect one ISP from pfSense, the gateway goes down due to packet loss and fails over to the other ISP as it should. When I reconnect the ISP, it never comes back up. I tried all sorts of things just as you have to resolve this issue, but nothing works. I rebooted the pfSense box and all WANs came back as they were supposed to.

@robh-0 Sir I m using only 1 ISP on my Pfsense route, I hooked it up to my other ISP to check the DHCP and the lan ports.
I m using only one static ip ISP on the Pfsense router, Which is just showing gateway down. I have restarted, Factory reset the router multiple times and still the same, I know the configuration is correct because i remember it very well, also the ISP technician had a look at the configuration and said it should work but it isn't. -
@apaar The issue I'm experiencing would occur if I only had one ISP.
What happens if you disable gateway monitoring? You really don't need monitoring with only one ISP.

@apaar said in Gateway offline, Packetloss:
incomplete
https://docs.netgate.com/pfsense/en/latest/monitoring/status/arp.html
"A MAC address listed as (Incomplete) indicates that the firewall has attempted to discover the host via ARP but it has not yet received a valid response."Can you post your WAN interface settings?

@steveits Sure!
-
Mmm, the gateway is not responding to ARP.
I assume you are connected to the LAN so it's unlikely the actual NIC is concorrect.
So I'd bet the ISP modem/router is blocking the MAC for some reason. Did you try rebooting that?

@stephenw10 i did reboot it, i will get it checked by ISP again. Thank you sir
-
The last thing I'd try there is to run a packet capture on the WAN and see if any traffic is coming into it at all.

@stephenw10 I have no clue about running packet capture, but i will try to do so.
-
@stephenw10 I did do packet Capture, at first it didn't work. But then the second time gateway showed online and then went offline within 30 sec. I can share the packet capture file if you want.
-
@stephenw10 Also now on the ARP Table it says WAN-Gateway- Expires in 651 Seconds.
-
Gateway Still showing offline and there is no internet.! -
Sure you can upload it to me here:

You might try swapping the WAN and LAN assignments just in case it's something the Realtek NIC is doing. Though they are both Realtek.

@stephenw10 Sure, I will try to swap them. Also i shared the file on the link.

I'm curious, if you reboot pfSense, does it then come up or does it stay down?

@ashishgupta09229 It is still down, even after rebooting and reseting the router. Everything is working from the ISP side as i checked it with my PC manually inserting the IPv4 on the ethernet adapter.
