More Information. Due to variations in the configuration, setting, and collaboration of technical devices, the digital image colors shown here may vary from actual samples. MASQUERADE This target is only valid in the nat table, in the POSTROUTING chain. It should only be used with dynamically assigned IP (dialup) connecÂtions: if you have a static IP address, you Source NAT. Used to "hide" the private source IP Address (i.e.:192.168.1.109), aka masquerading. To use masquerading, a source NAT rule with action 'masquerade' should be added to the firewall configuration: /ip firewall nat add chain=srcnat action=masquerade out-interface=Public. Above example shows you how to configure NAT on a Mikrotik Indeed Masquerade is the same as Src-Nat with the automatic selection of the external address as the source address. You need to use Src-Nat only when you have more than 1 external address (e.g. a subnet) and you want to specify which address is going to be used as the source of the NATted packet. NAT Masquerade (Many-to-one) First of all lets look at configuration settings to translate a network range behind behind a single IP. set nat source rule 10 source address '192.168../16' set nat source rule 10 outbound-interface 'eth2' set nat source rule 10 protocol 'all' set nat source rule 10 translation address 'masquerade' # NAT table rules *nat :POSTROUTING ACCEPT [0:0] # Forward traffic through eth0 - Change to match you out-interface -A POSTROUTING -s 192.168.1./24 -o eth0 -j MASQUERADE # don't delete the 'COMMIT' line or these nat table rules won't # be processed COMMIT Now enable the changes by restarting ufw. $ sudo ufw disable && sudo ufw enable FORWARD iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE service iptables save service iptables restart. Note: check if iptables is set to start during boot up. Or check the status of your iptables service: chkconfig -list iptables. If level 5 is on then it's ok othewise start the service at level 5 or level 2345.

Network Address Translation (NAT) is the process that modifies the IP address in a header of an IP packet, while it is travelling through a routing device. NAT allows one set of IP addresses to be used for traffic within a LAN (Local Area Network) and another set of IP addresses to be used for outside traffic.

Iptables nat masquerade hides the address translation using iptables. Address translation is possible using iptables. There is an inbuilt nat table in iptables. It includes PREROUTING, OUTPUT, and POSTROUTING chains. In addition, the masquerade is a type of network address translation. This allows hosts on a private network to use the public IP. Tables: Group of chains: filter and nat; Each chain has a policy - the default target; 8 What is Masquerading? All computers appear to have the same IP This is done with Network Adress Translation It's easy to fake the "outgoing packet" "Incoming packets" must be translated too Port translation - a must NAT Gateway. This topic describes how to set up and manage a Network Address Translation (NAT) gateway. A NAT gateway gives cloud resources without public IP addresses access to the internet without exposing those resources to incoming internet connections.. Warning Avoid entering confidential information when assigning descriptions, tags, or friendly names to your cloud resources through the Step-By-Step Configuration of NAT with iptables. This tutorial shows how to set up network-address-translation (NAT) on a Linux system with iptables rules so that the system can act as a gateway and provide internet access to multiple hosts on a local network using a single public IP address.
