NAT Question

Answered Question
Oct 15th, 2007

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

I have this problem too.

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.
