Do you want to set up the secured LAN connection? It is set up in organizations to work together. Proxy and Nat are two terms that are commonly used to set up the protecting secured LAN environment. This is system allocates for communication over the internet. The proxy server provides the level of security that applies to all the systems. The mitigate vulnerability of a proxy server directly effect on the main system.
Catch differences between the proxy server and Nat? The proxy server functions up to layer 7 of the OSI model while net functionality is limited only on 3 and 4 proxy. The NAT allows hiding the private address inland or making the use of public IP address lessen.
Proxy- Proxy is a dedicated software system runs on a computer or acts as an intermediary setup between a startup or and point device. Actually, it is a request between the user or client and the share of the proxy server on the same machine. Maybe, they use the same Firewall server or they use a separate server. But, they can request through the firewall.
Key functions
It works to provide secure internet application access to all the hosts.
Specific protocol
It has more specific protocols including FTP, HTTP.
Visibility
The server works as a middleman between two parties or servers. It helps to set up the connection and they are communicating well with the use of the proxy server.
Requirement of application
It doesn’t require any unusual software to operate the application.
Cost
It is costlier when you are opting to purchase the dedicated proxy device that performs better functionality.
The traffic flow
With the use of proxy IP address in, the source system directly sends to the traffic. They reach to the destination of IP by use of the proxy server. The proxy builds a new session with source and destination or IP and it works like a remote server.
Information or traffic control
It requires a high level of control when it works up to layer7.
Overhead
In proxy, all the packets are analyzed and after that, the action is started.
Benefits
It improves the control or security over the system or helps to access the outside of the world.
NAT-
It Alerts the IP address in an IP packet and permits people to communicate by use of public IP addresses. With their private IP address, they can set up the for Communication privately
Key functions
It helps to convert the private IP address into a public IP address.
Specific protocol
It is the least protocol-specific or more persuaded to the IP addresses.
Visibility
The communicating parties don’t know about the NAT services that are in the middle to set up the connection.
Requirement of application
Behind the proxy server, applications support the proxy services or it must be configured to use the server.
Cost
It is available in cheap prices and there is no need to get any dedicated network device. It can be performed easily on layer 3 or above devices including Firewall, router or various others.
The traffic flow
Like the remote server, the source system and send the traffic to the destination. This device converts the destination private IP into public IP.
Information or traffic control
It has inadequate phases of traffic control.
Overhead
It is less associated or simpler.
Benefits
It helps to hide a number of IP behind the small number of a public IP.
It is a great article that helps to catch the reliable or relevant information about the proxy server or NAT.
