Configuring pfSense with 3 VLANs - Problem to set ip [resolved]

[jwacalex]

Hi,
I want to setup pfSense to support 3 VLANs.
My setup so far:

Networking-Card: re0
vlan-interfaces:
re0_vlan1 (name: lan) static ip. set to: 10.0.1.0/24
re0_vlan2 (name: opt1) static ip, set to: 10.0.2.0/32
re0_vlan3 (name: opt3) static ip, set to: 10.0.3.0/24

when going to change the netmask for opt1 form /32 to /24, the following error occurs:
    This IPv4 address is the network address and cannot be used

i'm using: 2.1.5-RELEASE (i386) built on Mon Aug 25 07:44:26 EDT 2014 FreeBSD 8.3-RELEASE-p16

Can you tell me where the mistake in my configuration is?

Thank you in advance

set the ip's to x.x.x.1/24 instead of x.x.x.0/24
