Is it possible to do both port mapping and one-to-one NAT?
I recently changed ISP. Our external static range is a different range from the gateway subnet. Only way I could get it to work is to use one-to-one NAT for all my externally mapped IPs (maybe there's a way but I could not find it).
I had been using port mapping to create multiple services on the same external IP. But I can't find a way to do that when one-to-one NAT is used for everything .
Is there a way?
