You're missing the point; the 'new' machine won't be able to find an interface to emit the packets on in the first place, which is why they're getting 'no route to host'. If they want to do this, they should be using an interface route. In the above case, you'd use route add default -interface 206.27.32.1 but this loses in that your arp table ends up full of every host that you talk to. > The only way to legitimately do it is to use sub-interfaces on the cisco.

Just down the 'net from here is a pair of FreeBSD machines with a whole class C aliased onto an interface each; I'd say it works pretty well 8) > Paul. -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] "Who does BSD?"
