@AMOL ,
What error message are you seeing on the browser? I would suggest running a packet capture for the source you are testing from and see if any packets are being dropped by the firewall. You can use the following filter.
Navigate to INVESTIGATE | Packet monitor
- Settings tab: Uncheck everything
- Monitor Filter tab:
* Check “Enable Bidirectional address and port matching"
* Ether type: IP
* IP Type: TCP
* Source IP address: IP address of the machine you are tetsing from
* Destination Ports: 80,443,53
* Everything else clear
- Display Filter Tab: Everything clear, all boxes check
- Advance Monitor Filter: Everything check
- Click OK, and Start Capture.
- Please click on Refresh option on the packet monitor page to see the traffic.
Thank you!

Sounds like your content filter is blocking the site.
Hi @AMOL
Check MTU settings on the WAN interface(s). An incorrect MTU is the most common cause of web browsing issues through SonicWall UTM appliances.
Go to Manage | Network | Interfaces and click the pencil to edit the configuration.
Reduce the MTU size of WAN interface. For example reduce to lower value such as 1400 and try.
