About Router NAT Configuration Consultation

I have a C1111 router and I configured the following static NAT.

ip nat inside source static 192.168.2.190 172.25.139.241

ip nat inside source static 192.168.2.191 172.25.139.242

ip nat inside source static network 192.168.2.0 192.168.61.0 /24

I would like to know whether the third static NAT configuration will conflict with the previous two static NAT configurations?

What I want to achieve is that 192.168.2.100 and 192.168.2.101 are NATed to 172.25.139.241 and 172.25.139.242 respectively, and the other addresses of 192.168.2.0/24 are NATed to 192.168.61.0/24

I am not sure whether the newly added commands will conflict with the original NAT configuration.



No it WILL not conflict, you will be fine adding this, it will just create an additional permanent static mapping in the translation table along with the other two static mappings prior to any translation.
example::
Inside global               Inside local      
192.168.2.190           172.25.139.241
192.168.2.191           172.25.139.242
192.168.2.0               192.168.61.0
