I've figured this out now. No IP addresses on the etherip0 interfaces  
and then

boxA# ifconfig etherip0 tunnel 10.1.0.1 10.1.0.2
boxB# ifconfig etherip0 tunnel 10.1.0.2 10.1.0.1

i.e. the src and dst for the tunnel is not in any way the etherip0,  
but rather the physical interface in each box (rather obvious once I  
realised it). This did the trick and it is working fine.

Regards,

Johan
