IP Masquerade 1) is a networking function that allows a computer to act as an IP gateway that translates address 2) similar to the one-to-many (1:Many) NAT (Network Address Translation) servers found in:
- and network routers.
IP Masquerade is also known as:
- or MASQ for short,
- a Linux host is connected to the Internet via PPP, Ethernet, etc.,
- other “internal” computers are connected to this Linux host (via PPP, Ethernet, etc.))
the IP Masquerade feature allows the “internal” computers
- to reach the Internet as well.
- without any assigned IP address.
It allows a set of machines to invisibly access the Internet via the MASQ gateway.
It can be used with any lan connection (ethernet, …)
A masquerade would replace the source address:
- of the private IP addresses (which are not routed on the internet),
- by the public IP address of the server
Ip Masquerade vs NAT vs Proxy

- MASQ (1:Many)
- 1:1 (true) NAT
