This doesn't work for me (latest potato i386).

I can't ping the.new.ip.adr either, from anywhere.
Well. Several things: 1) There's no point in tracking RX or TX packets for a virtual interface (think about the word virtual for a while ...) 2) You're missing the "network" line from your iface stanza. Since it looks to me like you're adding a different subnet this is kinda important. 3) It doesn't look like you added any routes. This might not be necessary depending which kernel you're using. > I recompiled the kernel to turn on IP_ALIAS support. Is there another > feature I need to turn on, that I perhaps missed?

Consider whether you're helping us solve your problem by blocking out the IPs. -- Nathan Norman - Staff Engineer | A good plan today is better Micromuse Inc. | than a perfect plan tomorrow. mailto:[EMAIL PROTECTED] | -- Patton
