First, notice this: > > inet 206.123.101.20 netmask 0xfffffc00 broadcast > 206.123.103.255 Check out the broadcast address...it ends before the 206.123.104.1 address begins. The subnet you used for this entire contiguous block of IP's in human readable form is 255.255.252.0. This will only encompass the 101-103 supernet. There are two possible solutions. The first involves increasing the supernet to include the 104 block. The first ifconfig entry in your /etc/rc.conf file should be changed to this: # ifconfig_em0="inet 206.123.101.20 netmask 255.255.255.248 From: # ifconfig_em0="inet 206.123.101.20 netmask 255.255.255.252 The second option is changing the subnet for the 104 block alias in the rc.conf file. At this point, you have it set to 0xffffffff, which is 255.255.255.255. This is fine, so long as the 104 block was inside of the original subnet, but it is not. This is exactly why you are getting these errors in the messages log. You will need to find out how your IP's have been allocated to you. With this second option, you would change the first 104 entry's subnet to something different in the rc.conf file in order for it to be routed properly, such as 255.255.255.0. This subnet mask would encompass the 104 block, and only the 104 block. All of the other 104 entries shall keep their original 255.255.255.255 (or 0xffffffff) subnet mask as aliases. Either one of these solutions will work, but it may break other parts of the network if you don't know how the rest of the network looks at this. I'd assume you'd just want to take the first option as I bet that's what you meant. I don't have time to re-read this post, so if it is confusing in any way, my apologies. Feel free to ask questions. Also, any changes in this regard should be done at the console lest you make a mistake. After making changes to rc.conf, simply issue the command: # /etc/netstart To activate the changes.
