Or you can use a bridge. Speakeasy has their customers configure their
networks as a /24 even though particular customers normally only get
2 ip addresses. There is some filtering that goes on so that SE's equipment
does the equivalent of proxy arp so that you don't see other customer's arp
requests and your requests for other customers ip addresses will get the
mac address of the gateway (or DSL modem) as a response.
