ip nat translation

Hi,

there is one question.

By the customer is running a 7206vxr with 3 pools for address-translation.

One of this pools is the pool "car". This pool is running good, but there are not enough addresses to translate for network in access-list1.

"Overload" wil not be accepted from the customer, so i will configure a new

translation-network to the pool "car".

ip nat translation timeout 300

ip nat pool car 172.17.24.1 172.17.24.250 prefix-length 24

ip nat inside source list 1 pool car

Now the question :

Will the configured line be overwritten from the new entry,

or is it possible to have two lines with given networks for one pool?

Thanks!

Re: ip nat translation

Hi Ralf

If you define a new range on a pool with the same name it will

overwrite the old range.

So you have:

ip nat pool car 172.17.24.1 172.17.24.250 prefix-length 24

Define now:

ip nat pool car 191.168.1.1 192.168.1.250 prefix-length 24

The config will be:

ip nat pool car 191.168.1.1 192.168.1.250 prefix-length 24

Hope that helps

Re: ip nat translation

Hi roger ,

thank you for information.

The info does not make me happy.

The only way is, to integrate the network 172.17.23.0 to pool car.

The config will be : ip nat pool car 172.17.23.1 172.17.24.250 prefix-length 23

Now i will hope, that network 172.17.23.0 is free for use.

Thank you.

Ralf

Re: ip nat translation

You can also do something like this:

ee(config)#ip nat pool test netmask 255.255.255.0

ee(config-ipnat-pool)#address 172.17.24.1 172.17.24.250

ee(config-ipnat-pool)#address 172.17.23.1 172.17.23.250

ee(config-ipnat-pool)#^Z

ee#show ip nat stat
