dig problem with multiple network adapters

[David]

Hi,

I need some help to solve one problem:

I'm using BIND in a box with FreeBSD with 2 network adapters, the 
question is how force dig to use the second adapter.
In another box with  a recent dig version i solve a similar problem with 
the flag -b ( The  -b option sets the source IP address of the query to 
address. This
must be a valid address on one of the hosts network interfaces.)
But this machine is unstable, so at this moment I don't whant to make 
any kind of updates, can anyone tell me where  do I  configure dig to 
use the second IP address?

Thanks,

David.
