The problem I have is that my router sees my WAN port come up, gets a WAN IP address, creates a gateway, and then sees the WAN port go down all within 8 seconds or so.

If I put it on a static address, it behaves fine.


OPN Version: OPNsense 19.1.1-amd64
Cable Modem: Netgear CM500
Router: QOTOM-Q190G4-S02
NIC: Intel I211-AT- 10/100/1000 Controller


Franco suggested the following fix:  https://github.com/opnsense/core/issues/3197#issuecomment-463988437
But the same problem persists.

Can anyone mentor me through the steps to figure this out?

Here is a sample of my log:

Hello,

I'm setting up opnsense for the the first time and running across a problem I can't figure out..

I have a computer that has two interfaces (1) Intel NIC and (2) Realtek NIC.  My internet connection is with Comcast and I'm using a Arris Surdboard SB6141. 

If I assign my Realtek NIC (RTL8169) to the WAN device and connect to the SB6141, everything is fine.

If I assign the Intel NIC (NM10/ICH7 Family), then I have a ton of problems.  The device gets the WAN address from the cable modem but quickly (within 30 seconds) resets to being in a down state and seems to reinitialize.  It just keeps looping, WAN address assigned, Gateway opened, WAN connection goes down--rinse and repeat.

I can keep my connection working by using the Realtek connection for my WAN connection, but I'm trying to move to a QOTOM-Q190G4 mini computer.  That computer has 4 Intel NICs and the same problem happens on that setup. 

I have no clue how to troubleshoot this one.... All my searching has been for naught.  Any suggestions?
