Instability when multiple VLANs and rule editing.

FarmerB3d

Hi folks,

I have what I think is an odd stability problem.

I have the following:
WAN
LAN 10.10.50.0/24
OPT6 (trunk)
VLAN300 (parent is OPT6) 10.10.30.0/24

I have UBNT wifi kit with two SSIDs - Main and IoT
IoT is VLAN300

DHCP is working on both LAN and VLAN300.
I set up a rule on VLAN300 to route between main and it. I can ping from 10.10.30.50 (My phone on IoT) to 10.10.50.1 (LAN gateway) As expected, all is well.

So far, so good.

Now, if I play around with the rules on vlan300 such as disabling and re-enabling, things get weird. DHCP stops working and from time to time, internet vanishes for the main LAN.
This is pretty repeatable.

In the logs I can see my phone asking for IP address and the DHCP server offering one but my phone never seems to accept it.

The cure for all this? Reboot pfSense. Without fail, everytime, it will come right until I mess about with the rules again.

Am I missing something really daft? Any logs I can furnish to help diagnose this?

I am using the latest build.

thanks and Happy new year.
