pfSense

Steps to reproduce:
- Go to VGA console
- Option 2, Set interface IP address
- go through the wizard, when it asks you to enable DHCP say yes
- fill in the DHCP address range
- boom there goes the error, and it jumps back to the main menu
If you don't select enable DHCP, it sets the IP addresses correctly. As a workaround, you can assign a static IP to your PC, enter the web interface at the IP address set in the previous step, and enable DHCP from there - that doesn't crash.
