Gateway Offline -
-
So little back story I had my ISP switch me from DHCP to a Static IP they gave me my IP, netmask, and Gateway. I was able to access the gateway and internet no issues for 14hrs then it stopped and I have not been able to connect again and gateway says offline.
The ARP table shows the proper mac address for the gateway but no matter what I do it will not connect back to the internet. I hope there is something people can assist me with here.
I searched and tried different things as for other issues but this still persists.
Little Trouble Shooting.
Laptop - Works fine with the provided IP/SubnetMask/Gateway
Firewall Box #1 - Does not work with the exception of 14hrs.
Firewall Box #2 - Never worked -
@devilen
Try to state an alternative monitoring IP in the gateway settings, e.g. 8.8.8.8. -
@viragomann I have indeed done that and no internet connection avaialble.
-
@devilen Did you restart the dpinger service after changing the monitoring IP?
If not it will take a number of minutes for the change to register and the gateway to restore.
Checking Status-Gateways to see if it is reporting offline.
-
@rcoleman-netgate Yep, this was done.
Also, little more information My ISP also locks Mac Address every 3 hours but informed me they do not mac filter so switching between boxes 1 and 2 is a 3hr wait sometimes more or less depending on when the lock happened.
-
Something weird happened I don't know how to explain it but when I enabled the DHCPv6 on the wan the gateway popped up and started working. Is this possibly an issue or a known bug with PFSense?
-
@devilen Could be a DNS issue - that something internally is trying to use IPv6 for communication.
-
@rcoleman-netgate My ISP just contacted me that they assigned the IP to someone else and I need to change mine.
Mind you this is what I told them back on Friday (yes been dealing with them since Friday)
Thanks for the assistance everyone!
-
@devilen Sounds like the ISP needs to get it's act together.
Enabling IPv6 does mean you have another route out. Depending on how that's connected it could be a simple DHCP link or you could have a PPPoE push (not much else I can guess at here).
-
@rcoleman-netgate yes I am going to try to remove the DHCP now they gave me a new IP. yeah my ISP is small and only one guy is in charge of the IPs but because I've been dealing with this someone else contacted them complaining about network issues which is how he found the problem.
Even though I pointed this out to them on Friday of last week.
-
Is there only one IPv4 gateway on that firewall?
If so it should use that even if the monitoring fails and marks it as down. It will still be the default route.
If the gateway was still shown as current in he ARP table it is responding to ARP. You can check that by removing the ARP entry from the table. pfSense will imediately ARP for the gateway IP and it should reply, replacing the ARP entry in the table.Steve

@stephenw10 yep I saw your posts in other questions and I knew the ARP was working the gateway was working too but the problem for me was my ISP Gave the IP they gave me to someone else and didn't update their Sheet of IP's they have.
Everything is been working fine for a the past few hours. they are giving me till Friday to verify it works properly.
