pfSense

I sometimes get the following 'error' when trying to login to the webgui. (Today after performing a firmware upgrade to currentversion, comming from snapshot version of +-10 days old..) But ive seen it happen also after a regular reboot sometimes..(with 2.2.x also..)

Currently running: 2.3-BETA (amd64) built on Sat Feb 27 13:27:14 CST 2016 FreeBSD 10.3-BETA2

An HTTP_REFERER was detected other than what is defined in System -> Advanced (https://192.168.0.133:444/). You can disable this check if needed in System -> Advanced -> Admin.

.133 is the ip assigned by dhcp, which i normally use to access the webgui
.222 a virtualip of type alias
.111 is a carp-ip

In ifconfig output below it can be seen that the ipalias is configured 'first', but that should imho not cause the configured interface-ip to reject login attempts..

It might be that its related to my weird test environment with mixed dhcp and static ips on the same subnet.. But still i think all ip's on 'this-firewall' should be allowed to use for the webgui referer check.. Or at least that interface-ip which is supposedly configured 'on' the interface. As you can see the order changed, but that should be irrelevant..
