We had to put in a cisco 1605 router (with 2 ethernet ports) between our
net and our isp supplying our backbone connection.
The "ethernet", which is only a crossed 10BT cable between the two
routers, does it need real ip adresses?

Can I use 192.168.1.0-adresses here?
Or even unnumbered ip?
Our uplink isp wants us to subnet one of our C's in a /30, is this really
nessecary?
