NAT overload problem

Hello,

I want to Translate all my internal addresses on my WAN cisco's address.

I have followed NAT overload configuration sample in Cisco documentation, but that doesn't work.

No translations are perfomed for my internal adresses.

Could you help me ?

Re: NAT overload problem

Hello there,

It looks like you need to add the IP nat outside and IP nat inside commands to the relevant interfaces...

interface vlan 1

ip nat inside

interface fa0/4

ip nat outside

Give that a try and see what happens...

Cheers

Re: NAT overload problem

I've added this two statements on my conf (shame on me) but that's doesn't work too.

I've performed a "clear IP nat translation *" an restart a ping from my internal network to a WAN address but that's doesn't work.

I've attached new conf.

Re: NAT overload problem

Your config should work but try this as well:

ip nat pool test 192.168.2.8 192.168.2.8 netmask 255.255.0.0

no ip nat inside source list 100 interface FastEthernet4 overload

ip nat inside source list 100 pool test overload

That doesn't work too

But with "no ip cef" in configuration that's work (eiter with interface overload or pool overload) !!!

Why ?

Re: NAT overload problem

Hi Garnier,

Please add the following

You need specify nat inside and nat outside interfaces.

int fastethernet4

ip nat outside

int vlan1

ip nat inside
