Could it be something with busybox and/or the scripts cut the wrong 
piece from ifconfig?

Not using ppoe, standard ethernet with static ip. I've tried setting 
interface to the different interfaces (br0, vlan1). Atm the interface 
line is remarked. Also when ifconfig -a I can see that the ipsec0 
interface has the same MAC address as vlan1 (which should be right, I think)

ipsec0    Link encap:Ethernet  HWaddr 00:18:F8:3C:07:CB
           NOARP  MTU:16260  Metric:1

           RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

vlan1     Link encap:Ethernet  HWaddr 00:18:F8:3C:07:CB
           inet addr:  Bcast:  Mask:
