Unsolved FOG + Pfsense dhcp and vlan's: wrong subnetmask assigned

[frederiekvictor]

Hi,
I use fog in combination with pfsense dhcp and vlan’s.
Sometimes a wrong subnet is assigned at pxe boot. In that case, an IP address in assigned in another subnet, so fog does not start up any further.
sometimes subnetmast is correct and then of course it works. Unfortunately it is usually a wrong assignment.

Below my settings:

Does anyone have a suggestion where the problem might be?
