Hello to the community!

My first topic here, please allow me a stupid question :
In the IPAM database I have several subnets declared that I just for NAT on my Firewall. Let's take as an example 172.16.0.0/24.
This subnet doesn't have any logical devices inside, it doesn't have any VLAN associated (it is fully virtual) so my firewall allow me to use the 172.16.0.1 and 172.16.0.255 as NAT IPs. Unfortunatly, Infoblox doesn't allow me to reserve these address because it think these are network and broadcast adresses.

Any clue to allow me reserving these adresse ?

Thanks and regards,

Romain Pillon

Romain,

You should be able to create a reservation for the .1 and .255 addresses, even if they appear as being "used."

Unfortunatly, no. Here is the

Sorry Romain, I didn't qualified my previous statement.  You should be able to reserve the 10.15.0.1 address only.  The .0 and .255 addresses are bound to networking rules.  The first address is by default reserved for the network and the last address in a given network is for the broadcast. IB recognize this, therefore, you will not be able to reserve those addresses.
