I used to have a real routing /30 subnet, a long time ago. It worked exactly as you said: I had an IP address on that routing subnet, and my router had its own IP address on another subnet. My router used both addresses to route everything between them. Worked perfectly. Unfortunately, with the class of service I have, I no longer have this. Instead, I have a single address, negotiated through PPP (it's PPPoE). I don't have a routing subnet. Instead, I just have a simple IP address, with a unique property: some of its neighbors also get routed to me. So, it's as if I have multiple IP addresses, but I don't have a formal routing subnet, or anything like that. I'd like to be able to configure these "bonus" IP addresses, and teach my router about them. I've been able to do this in Shorewall by adding static ppp0:0, ppp0:1, ppp0:2, etc. devices. Each of these aliases contains one of my "bonus" IP addresses. The main ppp0 device gets its IP address automatically assigned during the PPP negotiation, as expected.
