Step 4: Create policies for Security Zone CORP that:
• Allow all outgoing traffic (with firewall policy priority 1024)
• Deny all incoming traffic (with firewall policy priority 1021)
• Create an object of type http-filter to block java traffic
• Modify policy 1024 to pat all outgoing traffic using public IP 193.168.94.220
• Modify policy 1024 to add a java HTTP filter.
