I've searched to forum and other people have asked this question, but so far there doesn't look like there is an answer.

Is there a way to specify the outside address of a Masqerade? This would be like the way that cisco does it. After that question, is there a way to have a masqerade pull from a pool of addresses, again like cisco?

Thanks for any clues...

use 'src-nat' instead of 'masquerade'

Will src-nat go to an address pool instead of a specific address? Say 24.205.129-132?

yes, set 'to-addresses=10.24.205.129-10.24.205.132'
