lets say u ur internal mail server ip address is 192.168.1.1. make static nat for this ip to one of the public IPs. then go to ur server give it a secondary IP lets say 192.168.1.10. and then mak another sattic nat maping the second public ip address to that secondary IP. this case will for sure. good lcuk . and let know
Example: Connect a private subnet to the internet using NAT. On the one hand we know how IP packets look like, on the other hand we are ready to manipulate packets under Linux (and other Unix derivates). Therefore we are ready for our first application! The most popular question regarding NAT seems to be the one about sharing an internet Understanding NAT - VMware IP addresses
What is Network Address Translation (NAT)?
5.3. Stateless NAT with iproute2 - linux-ip.net The NAT code has substituted the real IP of the server, 192.168.100.17. This rewriting is handled by the nat entry in the local routing table (ip route). See also Example 5.2, “Basic commands to create a stateless NAT”. What is NAT? Network Address Translation or NAT refers to a specific process that involves remapping a single IP Address into another, often times Public, IP address through altering the network information and address information that is found in the IP header of the data packets. Local networks have several private IP addresses that pertain to specific devices in the network.
Network address translation (NAT) is a networking feature that helps you connect environments that have overlapping IP addresses. NAT prevents IP address conflicts by mapping a unique IP address to every VM on a connected network. This NAT IP address is used for inbound and outbound communication with the NAT-enabled network.
NAT translates the IP addresses of computers in a local network to a single IP address. This address is often used by the router that connects the computers to the Internet. The router can be connected to a DSL modem, cable modem, T1 line, or even a dial-up modem. Network Address Translation (NAT): A NAT (Network Address Translation or Network Address Translator) is the virtualization of Internet Protocol (IP) addresses. NAT helps improve security and decrease the number of IP addresses an organization needs.
