By default, most machines do not perform packet forwarding, since RFC 1122 prohibits packet forwarding by default. You'll have to find out how to turn it on on the HP. This could be as simple as setting a parameter. For example, in FreeBSD you just enter: # sysctl -w net.inet.ip.forwarding=1 It's more likely, though, that you're going to have to build a new kernel on the HP with the option IPFORWARDING. I don't know HP, so you'll have to find out some other way. > Could some kind soul give me some words of wisdom here. Also does the > Hp need 2 hostnames now that it has 2 IP addresses? Well, you don't need two IP addresses for the two interfaces. You can use the same address for both. But if you want to leave it that way, no, you don't need another name, and it's not a good idea.
