Trying to setup a new box with i226 NICs so fresh install of the ISO and update from fresh 2.6 install both have the same result.

jimp

I can't replicate that here on a fresh install with or without additional interfaces (static and dynamic).

I can see in the code how it might be a problem I just can't seem to make it happen here yet.

Did you alter the configuration in any way directly? Or was the configuration restored from an older system?

thestryker6

Completely fresh installs all around and initial setup done with a single NIC active with dynamic IP (I tried a USB NIC and one of the 4 i226s during separate attempts). When I tried installing 2.6 with the USB NIC and then updating to 2.7 the DHCP Server page loaded as expected on 2.6 but then had the error after updating.

jimp

OK, so you just had "wan" and no other interfaces assigned?

EDIT: Must be, if I remove all but the WAN I do see the errors you see.

I'll work on a fix, thanks!

thestryker6

Yeah that must have been it, because I just reset everything and made sure to setup a LAN interface as well and I was able to see everything now.

jimp

OK, the errors you saw should be fixed on future snapshots.
