<![CDATA[VLAN Configuration]]>Hi All,

i have installed a pfSense machine along with 3 NIC's: 1xWAN 1xLAN(Intel Desktop Pro 100S) and 1xOPT, now i'm trying to configure some VLAN's on the LAN interface, which is connected to a c3560 switch in access port.
Whcih settings should i set on the pfSense in order to work with VLAN's?
I'm adding the corresponding VLAN's under Interfaces: Assign->VLANs then under interface assignments i'm attach the VLAN's to the LAN NIC (fxp0) and press save….then i'm loosing connection to te pfSense!
Where do i wrong? should i change to port on the switch for trunk mode?

Thx in advance!

Don't use both on the same IF!

switchport trunk encapsulation dot1q
switchport mode trunk
