I have two ips inside my lan fe0/0/0,

need to translate three public ips to them,


two, to 1, and 1to 1

as follows


189.231.33.12 coming from outside should nat to an inside ip of 10.0.0.10 189.231.33.14 coming from outside should nat to an inside ip of 10.0.0.10


and

189.231.33.15 coming from outside should nat to an inside ip of 10.0.0.21


considering this is the only NAT on the config, and the interfaces are:


fe0/0/0

and

S0/0/0


how this nat should be setup,


thanks

hey,

the syntax might be wrong but i know the concept:

1.

put the "ip nat inside\outside" on the relevant interfaces.

2. on global config:


ip nat inside source static 10.0.0.10 189.231.33.12 extendable


ip nat inside source static 10.0.0.10 189.231.33.14 extendable


ip nat inside source static 10.0.0.21 189.231.33.15


you need "extendable" because you map the same inside ip.
