Public IPs assigned to Sonicwall

My Sonicwall connect to a ISP router. The provider provide 2 set of public IPs.

How can my sonicwall use these two set of public IP address ? Currently, one public IP has been binded to a WAN link of sonicwall but I have no idea how to make use of another one ?

WIth the other IP you can setup 1 to 1 Nat to access an internal server or setup PAT to access services on diffrent internal servers like ftp or RDP

check out this Video, it explains NAT Policies.

Suppose my ISP give me two public IP range : / 29       (6 hosts)     / 29        (6 hosts)

Currently, my firewall has already use (as my Sonicwall WAN) and for my router.

But, how can I make use the other subnet on my Sonicwall to use the other subnet ?

You can take advantage of the entire range by defining them in Address Objects. This is how your breakdown will be for this example.

CIDR Network:     
Network Address/ID:
First Host Address:
Last Host Address:
Broadcast Address:

Typically, you'll bind the First available IP or First Host to the WAN ( in your X1 port. To utilize the other Hosts/IPs ( simply create Address Objects such as X1 (.3), X1 (.4)...and so on (or whatever you want to name them - it doesn't matter as long as you know what they mean).

Then you can use those Address Objects in your firewall for Access Rules, NAT Policies etc. You can setup DNS records (A Records, etc.) in your external DNS servers to route the traffic accordingly. For example, if you wanted to use your third available IP for RDS traffic you could setup something like ( then in your firewall create the appropriate Access Rules and NAT policies to route the traffic to your RDS server internally. I'd recommend to do so via the Wizard > Public Wizard.

My provider provide me with two non-contingent subnet.

 We have already binded as my Sonicwall WAN with gateway (my router).

As the ISP provider another different subnet, which is  / 29. How can I make use of this subnet ?
Blue Street TechLast KnightCommented:
So you have a 10 pack of static IPs and this is how they distributed them to you in two different IP blocks?

If that is the case I'd contact your ISP but I'm thinking that they have bound both subnets to their equipment so that you should be able to get both networks on the same uplink to their router. Check with them but if I'm correct, then simply do what I said in my last comment but with the new subnet as well. Maybe for the Address Object Naming something like X1 1st block (.3), X1 2nd block (.3)...etc.

To clarify my understanding,

Two subnet range / 29       (6 hosts)     / 29        (6 hosts)

Sonicwall WAN    :  
ISP router            :

So, I can simply setup other public IP (, similar to without need to anything on the WAN link, correct ?

Normaly you only need to add an arp entry with the subnet and bind it to youre wan mac
then add network objects for the ip addresses.

after this you can use them for natting
