asterisk users - Feb 2011 - Multiple public address to one Asterisk server behind NAT?

I have a situation where an Asterisk server is NATted, sitting behind a PIX. 
One public IP is used for one purpose, now a second public IP is required for
another.

Is there a way to have Asterisk use more than one public IP when behind NAT?  (I
already use the externalIP setting)...

If not, any suggestions for a SIMPLE way to do this?

Thanks

"Dumb" answer - bind to 0.0.0.0 - the externalIP setting probably
trashes
this idea.

You could run two copies of asterisk on different private IP addresses.

Have your current install bound to the first private IP with the
externalIP set to the first public and the second install running on
the other IP with the other externalIP set.
