Hey, What I'm trying to do involves FreeBSD and IP aliases. Hopefully someone has some ideas. Here's the general idea of what I'm trying to do:
I've got vr0, which is assigned to some IP address... let's say: 192.168.1.90 with a subnet mask of 255.255.255.0. This is all fine, and everything works. I'm implementing a protcol called ArtNet (which I didn't design) which uses 10.x.x.x network for controlling lighting. It's all UDP, and uses broadcast packets to 10.255.255.255. IP addresses of hosts are determined by a sort of shitty algorithm based on the MAC address, and can appear anywhere in the class A. This allows: a) IPv4 (yes, I know IPv6 would be better) and b) autoconfiguration without the need for a DHCP server. I didn't make it up, I'm just trying to make my stuff work with it. So, here's the deal.... I want to add 2 aliases to vr0 so that I can run 2 ArtNet services on the same machine. So, the aliases would look something like this: 10.0.38.237 netmask 255.0.0.0 10.255.38.237 netmask 255.0.0.0 Adding the first one like this works: ipconfig vr0 inet 10.0.38.237 netmask 255.0.0.0 alias However, adding the second fails, I'm assuming because the netmasks overlap. I can understand why this is so, but for my application I actually want this. Because programs listening on both addresses both need to receive broadcast packets sent to 10.255.255.255. So, how can this be done? Adding a second NIC is not an option.
