Just looking at you IP address and netmask, they look wrong. 130.226.145.156
is a Class B address, and you are using a Class C Netmask.  It looks like
that is a valid ip address since it belongs to the Danish Network for
Research and Education, and you are in  .dk domain, so check with your
system admin and see if your netmask is not supposed to be 255.255.0.0.  Or
some weird subnet :)
Looks like they are using the whole thing, though, from the address of your
main router being .1 as it is below...

That's all I can see from here, so if that doesn't help maybe some
networking god or goddess on the list can shed some more light on the subject :)
