What most people think of a NAT box is truly a PAT (Port Address Translation). One external IP and many internal IP addresses. In this case, both the IP address and the originating source port are translated. That's because you need to tell to B where to find the server that converts domain names like www.gnu.org into an ip address. Copy the file /etc/resolv.conf from A to B .

The server is statically port NATed from my one public IP to an address on VLAN1. The Linux Virtual Server (LVS) analyzes packet per packet and applies load-balancing rules using layer 3 and layer 4 information. LVS does not hide the client IP address. However, in some cases, it can be useful to change the source IP address to ensure that traffic passes through the ALOHA when in LVS destination NAT mode:

For the maximum security of your data, it is highly recommended that you use a VPN that has an in house Nat Firewall. Such firewalls are usually way more sophisticated than basic NAT and have more functions to protect your data. RusVPN is an outstanding VPN service with secure and fast servers …

Network Address Translation (NAT) is the process where a network device, usually a firewall, assigns a public address to a computer (or group of computers) inside a private network. The main use of NAT is to limit the number of public IP addresses an organization or company must use, for both economy and security purposes.
