Gateway offline, Packetloss
-
@stephenw10 I have 2 ISP’s one for the home network, which is running on dynamic mode and the other ISP is on static for my home servers. So i tested the dhcp lease on my home network which is running the dynamic ip and i just set the configured the pfsense to Dhcp mode and it grabbed the ip and the local gateway of the router.
But with the other ISP in the static mode the gateway is showing offline and 100% packet loss. -

Do you have the correct gateway/settings?
Is the subnet set correctly on that WAN? (if not, your IP maybe can't reach its gateway) -
@steveits I did check the IP and the gateway and set the subnet to 24 bit for 255.255.255.0. If i m correct.
-
If you connect a PC directly to the static config ISP and set those same values does it work as expected?
-
@stephenw10 yes it does.
-
Ok then either pfSense is not using the interface as expected or the ISP is not allowing it.
Perhaps the interface assigned is not the one you're using. Or maybe the ISP has blocked the MAC address.
Do you see the ISPs gateway as a complete entry in the ARP table? In Diag > ARP?

@stephenw10 The interface is detecting on the other ISP, But the ISP wont block the mac address. I ll check the table.
-
@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.

"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?

This post is deleted! -
@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.
