Sure, but normally, either .1 or .2 of a /30 subnet (ie, your .241 or .242) is the externally-connected router of your ISP. A few of the better ISP's will support switching their devices from being a router to acting like a bridge, thus requiring you to provide a dual- homed machine yourself. How else are you going to provide a default route except by using an IP which is reachable on that subnet...? -- -Chuck
