what's the big difference betwen MASQ and PAT(nat)?

Hello, 

I read what MASQ is doing and it sounds like PAT to me. 

Is there any difference between MASQ and PAT?

Because hiding inside network or device? PAT does the same thing.

Thank you.

  • PAT is more likely something based on Ports. The P stands for Port translation. A MASQ (SNAT) is to translate the source IP of a network/IP to the Interface IP of the firewall.
