Cant find the Options on the Screenshot
ive got an Multi-VLAN enviroment.
On the following picture i can see some option to define for each vlan an DHCP relay.
My pfsense 2.1 shows an other gui?
You can change the theme of pfsense web gui, so if that is what your asking - but all the items should be there. You can not setup relay or enable it if you have dhcp server enabled on any interface.
To see that screen you would need to disable pfsense dhcp server.
You can change themes on the bottom of general setup, I like nervecenter - but I don't believe it is default theme?
