I actually tried that already aswell but it didn't work. So I added
device	tap
in the kernel, recompiled and still the same problem

FreeBSD# kldload if_tap
kldload: can't load if_tap: File exists
--> I guess because I compiled it in the kernel

FreeBSD# ifconfig tap0 create
ifconfig: SIOCIFCREATE: Invalid argument

FreeBSD# ifconfig tun0 create
ifconfig: SIOCIFCREATE: Invalid argument
--> get the same for a tun interface
