Solved: NATing issue

marwansiala · ‎03-28-2010

i am trying to configure NAT with overloading option.

we have 16 static IP from the ISP, we use most of them as static nating for our servers.

we need to use one or 2 static IP addresses for all the users to connect to the internet (NAT + overload).

i have looked it up to configure it, we can use this commant to do it:

ip nat inside source list -access-list name- pool -pool name- overload

i have 2 questions now if i may ask:

- am i in the right direction? or i am totaly lost

-how can i define a pool of addresses? can i assign the addresses i need?

thank you for your support

Yes this is the correct way to do it.

To define the pool -

ip nat pool NPL 195.20.1.10 195.20.1.11 netmask 255.255.255.248
