On my server (FreeBSD 9.2-RELEASE) I have several aliased IP addresses from one subnet:

192.168.0.1/24
192.168.0.2
192.168.0.3

And I am wondering how to correctly detect to wich particular IP a client is connecting to (the remote host IP - src-ip - is known)?

The main problem is that a client can already be connected to one IP and I want to know whether it is connecting to another IP-address.

The final goal is to accept or deny a connection based on the username (it is known) and dst-ip of client.

Actually I want to dinamically assign bootfile-name based on clients MAC.

I have tried this config:

option bootfile-name concat( binary-to-ascii(16, 8, "", substring (hardware, 1, 6)), ".cfg");

But this is wrong config (as dhcp server isn't starting at all). If instead of concat(...) I put just real filename (e.g. "000102030405.cfg") everything is ok. But this is not what I need. Is there any way to dynamically set bootfile-name?
