I'd definitely need to spend some time studying these articles some day :-)
Do you know where I can find them?

I assume you're talking about the Archimedes/RiscPC Econet modules. Since I
don't have one of these machines (yet) I don't have any experience with
this. But then again, it wasn't my intention to set up a machine as a
gateway.

Indeed I'm doing this for fun! What I'd like is to have a stand-alone device
like a router/switch etc. so I don't have to 'sacrifice' an
Archimedes/RiscPC.

I've had this idea of an Econet-Ethernet gateway for some time now. Not
because I'd want to sell them and make profit out of them, but merely for
fun and 'to see if it can be done'. Now I find that more people are
interested in building an Econet-Ethernet bridge, which is great, since we
now can share ideas and thoughts. Don't know about others, but my intention
is that when the device is ready, the schematics/PCB layout/documents should
be available to the general public. If anyone then feels like selling
pre-built devices, go right ahead, but that's not my intention...

No problem :-) I'd rather have someone warn me about something I already
know, than someone telling me afterwards: hey, did you know that......

Do you know where I can find them on the net?
