It probably only got a fe80:: (link-local) address. fe80:: are not
routable, and you probably have to specify the scope (in this case the
interface name) to get it working. So, fe80:<fill in>%eth0. But generally
speaking it is a very good idea to assign at least a site-local address to
the interface (site-local functions comparable to 192.168.0.0/255.255.0.0
in IPv4). Site-local addresses start with fec0::. An example of how to set
this up can be found in :

http://www.linuxpackages.net/howto/s...netconfig.html

It will probably work without a hassle if both interfaces have a
site-local address.
