Ip masquerading vs nat
Let's say we want all outgoing traffic to appear coming from our WAN address 1.1.1.1 so we create a masquerading rule like this: Internal network group --> WAN interface: use address 1.1.1.1 Why can't I just create a NAT rule: The quick answer is to use SRC-NAT if your gateway IP is static, and use masquerade if it can change. The Mikrotik Wiki Entry Firewall NAT action=masquerade is unique subversion of action=srcnat, it was designed for specific use in situations when public IP can randomly change, for example DHCP-server changes it, or PPPoE tunnel after The following command will enable IP Masquerading in Linux Firewall: $ iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE. The above rule will use NAT table (-t nat) on built-in Postrouting Chain (-A POSTROUTING) on interface eth0 (-o eth0). The target Masquerade (-j MASQUERADE) advises to mask the above matched IP packets from the related The masquerading will change the source IP address and port of the packets originated from the network 192.168.0.0/24 to the address 10.5.8.109 of the router when the packet is routed through it. To use masquerading, a source NAT rule with action 'masquerade' should be added to the firewall configuration: Dynamic NAT – Dynamic NAT allows unregistered private IP address to be translated into registered public IP address from a pool of public IP addresses. PAT/ NAT Overloading/IP masquerading – PAT is most popular type among the three types. It is a variant of Dynamic NAT and is similar to it, but it maps multiple private IP addresses to a (IP Masquerading again) So, in a nutshell – NAT allows you to ‘see’ other IP Subnets while keeping you anonymous to those other networks.

A typical scenario where we generally use SNAT is when we are required to change the private (i.e. RFC1918) address or port into a public address or port when the packets are leaving the network. IPtables中可以灵活的做各种网络地址转换（NAT），网络地址转换主要有两种：SNAT和DNAT。SNAT是source networkaddress translation的缩写，即源地址目标转换。比如，多个PC机使用ADSL路由器共享上网，每个PC机都配置了内网IP，PC机访问外部网络的时候，路由器将数据包的报头中的源地址替换成路由器的ip，当 IP Masquerade is also known as Network Address Translation (NAT) and Network Connection Sharing some other popular operating systems. It is basically a method for allowing a computer that doesn't have a public Internet wide IP address communicate with other computers on the Internet with the help of another computer sitting inbetween it and the Internet.

Whenever the Internal network wanted to go to the Internet, it associates an available VALID IP address from the /ip firewall nat add chain=dstnat action=dst-nat dst-port=2200 p rotocol=tcp to-addresses=10.11.12.14 to-ports=22 in-interface=PPPoE-to-Dlink. None of above works with current src-nat nat rule; but if I use masquerade instead, it'll works! note: I test each I read that masquerading translates many private IPs to one Public IP, but doesn't NAT already does that? I'm trying to understand what masquerading is to determine if I need a masquerading entry (in NAT window) for each Hotspot network? I've noticed that in the line "IP masquerading cannot provide full internet connections to the hosts which hide behind it" does this line imply for nat?

Differences. MASQUERADE does NOT require --to-source as it was made to work with dynamically assigned IP addresses. SNAT works with static IP addresses. The main difference between NAT and PAT is that NAT is used to map public IP addresses to private IP addresses, it could be a one-to-one or many-to-one relation. On the other hand, PAT is a type of NAT where the multiple private IP addresses are mapped into a single public IP (many-to-one) by using ports. This NAT mode is also know by other names, like NAPT (Network Address Port Translation), IP Masquerading and NAT with PAT (Port Address Translation).
