nat translation to dynamic IP - need help, urgent!

[wijaya_ivan]

hello,

i need help regarding configuring nat in cisco router.

my router is connected to ISP and the ISP give a dynamic IP.

the problem is how i use nat if the global inside is dynamic?

because ip nat pool command need a fix IP address right?

so how i translate my private ip to a global ip but the global ip i got is dynamic?

Thanks

Hi Ivan

Have you explored of doing a overload onto the interface which is connecting to your SP and configured as an nat outside interface ?

for more info on the same do refer this link..

ip nat inside source list interface overload

Hi Ivan

As also mentioned by the other poster you need to configure the ACL permitting your network which is required to be natted (to which you need to provide internet access) and the outside interface as i mentioned in my earlier mail.

Hi,

Did you try the next NAT command:

ip nat inside source list ACLNAT interface "outside interface of your router" overload

In the ACLNAT you can define the IP range of your internal network....
