Hello everyone. I have an issue here that started around 8 pm last night and I am not really sure what to do here. Basically every 1-2 hours (its been 2 hours so far this morning) the WAN DHCP Gateway on pfSense is going offline and I am getting packet loss. The internet is down at this point. Now if I wait long enough it seems like it will eventually come back up (at least an hour but it has taken more). If I just disable the WAN interface on pfSense and then re-enable it, the internet comes back up and is good for another two hours. My setup is fairly simple. I have ethernet from the ONT ----> pfSense WAN Interface. The Verizon router is connected through its lan port to switch which uplinks to the pfSense. I followed this guide when I set everything up https://nguvu.org/pfsense/verizon/pfsense-verizon/. All the TV services work great and even the caller-id and remote DVR functinos are working. Now I looked at the DHCP logs and it seems like it is trying to renew DHCP every 3600 seconds. From what I have seen this morning, the first renewal goes through and it binds to the same IP it already has. However, when it goes to do it again an hour later, it keeps sending requests to the gateway but gets no response. Eventually it sends a request to 255.255.255.255 and gets a response from a gateway. This is what happens if I power cycle the ONT or Disable/Re-Enable the WAN interface on pfSense. I will post a small amount of logs from this morning below but I can post more if needed. Any idea what I should do here? This have been working fine for 2+ years now and all of sudden last night at 8 all hell broke loose. I haven't called Verizon yet but I may have to do that soon. It is just difficult to talk to them when you have your own router because sometime they don't want to help. Sorry for the long post. I apppreciate your help and time. Thank you.

Hey sorry everyone. Didn't realize it would format it this way. I am going to repost my post below but I have a pastebin link for the logs. Hello everyone.

It is very likely that Verizon will not help you.  They do not support non-Verizon routers nor do they get into technical details like this.

 

Two hours is the standard timeout for WAN IP leases on FiOS.  A renewal at half the expiration time, or 3600 seconds, is expected behavior.

 

It sounds like something about the way the pfSense is issue the renewal request is different than what a Verizon router does.  I don’t know what that could be.  If you are handy with WireShark you could hook up your Verizon router as primary and watch what it does.

 

If there is a pfSense user forum, you might be able to get some answers there if no one here has any experience with this issue.

 

Good Luck.
