this is what i tried to do in my first attempt. i'm not exactly sure why
it failed but i thought it could be due to the fact that i have the same
subnet on two interfaces and hence the router wouldn't know on which
interface a packet should be placed.

my intention to use routed was to allow multicast packets to be passed and
hence "merge" the two subnets. i'm absolutly unsure if this is really what
routed would do or how to solve this problem at all. any help would be
greatly appreciated.
