Hi again One more question, how to do NAT in sonicwall firewall?

Actually we have a Lease Line with one WAN ip and 5 LAN ips, how to do NAT configuration to given 5 LAN ips to my internal private ips?
for ex:
my WAN ip is - 1xx.xx.xxx.xx /30- (a)
Given LAN ips are 1xx.xx.xx.xx0/29 to 1xx.xx.xx.xx4/29 (b)
I wanted to do NAT configure as my internal private ip like 192.xxx.x.xx0 to 1xx.xx.xx.xx0/29 (c)
So that we can access even internally as well as externally...

hello @Manoj ,
Can you clearfy network topology with viso design ?
If I'm not mistake. You have LL router and there are 2 interfaces and behind the router located sonicwall fw?
<--Wan IP 1.x.x.x/30 eth0 -->
LL ROUTER<-- Lan ip eth1 1xx.xx.xx.xx0/29 to 1xx.xx.xx.xx4/29 --> <--X1Sonciwall FWX0 --> 192.xxx.x.xx0 to 1xx.xx.xx.xx0/29Assuming your provider is routing this /29 to your "1xx.xx.xxx.xx /30" IP address, then create an address object for the public IP of choice and use it in a NAT policy.
If you use the /29 just for NATing rather than routing then you actually have 8 IPs to work with, not 5.
Hi all,
Thank you for the response, I just figured it out.
We have one WAN IP from one of the ISPs -------- (A)
Five LAN executable IPs from ISP -----------------(B)
Our internal Private IP ------------------------------(C)
What I did is I configured
single WAN IP from ISP as a WAN in our firewall --- (A)
added address objects Five executable LAN Ips from ISP --(B)
added address objects my private IP ------------------------(C)
Configured NAT policies as below,
1st Original to Translated ----
any to any
(B) to (C)
service - original
any any
2nd Original to Translated
any to any
(A) to (B)
service - original
any to any
Now that it, it's communicating even from outside the network with a single WAN IP with distributed executable LAN IPs
hope it will be helpful for others too.
Just to reiterate, you have 8 public IPs, not 5.
Yes... Okies ..Thanks ..
