A little info about what you've done might be helpful, as my crystal ball is in the shop again.

I create in Vm a windows server 2012r2 and I set the hyper V.
Then I create 2 virtual switches one external and one internal. I create a vm in hyper v for pfsence and when Istart the installation I try to configure a WAN 192.168.1.25 4 subnet mask 255.255.255.0 and when I set LAN 192.168.100.1 it tells me not in subnet
