I would recommend reading up on masking in your copious free time. Suffice it to say that, in this case, the following is true: xxx.82.15.208 - xxx.82.15.223 is the address range, with .208 and .223 reserved. If you want to have your aliases attached to the tl0 interface, you need to use addresses in that range. So, something like: ifconfig_tl0_alias3="inet XXX.82.15.210 netmask 0xffffffff" Also, I would recommend using the .209 or .222 address (first and last useable in the subnet) as your tl0 (default gateway) interface. It's standard operating procedure and will help you in the troubleshooting process to have things fairly standardized. If you set your interface to .209, then you could set interface aliases from .210 to .222 inclusive. Mike -- Michael K.
