Multiple bind's on one box

[Archive User]

Hiya,

I would like to setup a bind server so that 
one copy of bind listens on my external Internet 
address and another completly seperate copy 
listens on my internal lan address. I see that 
bind has a listen-on option but can it be used 
to run multiple copies of bind at the same time? 
Am I going to have any disadvantages to do this? 
How will ndc work in this case? 

These servers will be slave servers to my 
internal master bind server and my external 
master bind server (split dns). 

I am currently running bind 8.2.2p7. Unfortunatly
going to 9.x is not an option at my company right
now.. (they are afraid it is to new and has bugs). 

Thanks for any info you can offer.. 
Mike
