Ip masquerading vs nat
With LVS-NAT, the incoming packet (src=CIP,dst=VIP, abbreviated to CIP->VIP) is rewritten by the director (becoming CIP->RIP). Network Address Translation (NAT): NAT, in which the Private IP address or local address are translated into the public IP address.

Network Address Translation is the name for a box that would have a pool of valid IP addresses on the Internet interface which it can use. 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? IP masquerading is just another name for NAT/NAPT, commonly used on Linux systems. Both mean the same thing. IP masquerading allows you to use a private (reserved) IP network address on your LAN and have your Linux-based router perform some clever, real-time translation of IP addresses and ports. When it receives a datagram from a computer on the LAN Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device.

In Linux, we use a term called IP Masquerade. This page explains how to set up NAT and FORWARD firewall rules for WireGuard in Linux. (Redirected from IP masquerading).

Previous page. Table of content. As of RFC 2663, NAT and IP Masquerading are the same thing. Once upon a time, NAT required your own externally addressable subnet (you'd have had to pay for your own class A, B, or C address block). DNAT (Destination NAT): Simply changes the IP address in the destination header of the IP packet and sometimes TCP / UDP port as well Masquerading: Is similar to SNAT, although it is unaware of which IP address it will be NAT'ing against at the time of rule # # Each IP Masquerade network needs to have at least one.

private IP-Adressen) durch mehrere Hosts. En réseau informatique, on dit qu'un routeur fait du network address translation (NAT) (« traduction d'adresse réseau » ou « translation d'adresse réseau ») lorsqu'il fait correspondre des adresses IP à d'autres adresses IP. En particulier, un cas courant est de permettre à des machines disposant d'adresses privées qui font partie d'un intranet et ne sont ni uniques ni routables à l Continuing on from the initial scenario, lets now assume that we wish to apply IP masquerading, this would an example of a source NAT.
