Dynamic nat from one source network to multiple destination networks

My situation is this - I'm merging three old PIXs into one new PIX525. Each PIX's inside interface is connected to the same network, but their outside interfaces connect to different destinations. Each was configured with dynamic NAT. If I try to use dynamic NATs from the old PIXs in the new PIX, I get a "Duplicate NAT entry" error. I realize that I could combine static and dynamic NAT to get around this, but I'd rather not if possible. Has anyone run into this? One possible caveat, the old PIXs are running PIX 4.4 OS

Re: Dynamic nat from one source network to multiple destination

What exactly are you typing into the new PIX, I don't understand what you're doing. Please include the nat/global statements from your 3 old PIX's and then include the text from when you enter the new commands and where you get the error.

Thanks.
