or you can keep your secondary addresses to a loopback interface: ifconfig create lo1 ifconfig lo1 200.200.200.1/24 ifconfig lo1 alias 200.200.201.1/24 ifconfig lo1 alias 200.200.202.1/24 ifconfig lo1 alias 200.200.203.1/24 ifconfig lo1 alias 200.200.204.1/24 etc > If this is possible is it accomplished via a special routing? No, nothing special. Your box has: network1.address1 network2.address1 your upstream router has: network1.address2 network2.address2 If your router is willing to forward packets to/from your addresses, everything will be correct(read bellow though). > My concern is that I have a laptop with one network > interface, built in, but would like to access it both at > a public static address and a private network address. > Is this possible? > Your private network address will not be routed by your ISP. You have to use "real", routable addresses. These are routable across the internet, the private addresses aren't. They are for private use and should be filtered. Please give more information, if I didn't cover your questions.
