map says:

given input x, provide y

So, if input 61023, provide 179.x.x.x.
If input 61023, provide 172.25.120.2.

So, one input can only have one output.

They are the result, not an input.

ip daddr 179.x.x.x tcp dport 61023 dnat to 172.25.120.2
(its not clear to me if you actually want daddr or
ip saddr 179.x.x.x/8 tcp dport 61023 dnat to 172.25.120.2).
