Static NAT for a complete subnet

Hi,

Is it possible to statically NAT a complete subnet?

I have a need to NAT 10.10/16 to 172.168/16 where 10.10.x.y is NAT to 172.16.x.y.

How can this be done?

Rgds,

Elil

Hello Elil,

yes it is possible the

ip nat source static command accepts a network option

this can be very handy in some migration scenarios

p nat inside source static network local-network global-network mask [extendable | no-alias | no-payload | mapping-id map-id | redundancy group-name | vrf name]

see
