Twice NAT - Network Address Translation

Every type of address translation we've discussed so far has one thing in common -- only the Source IP was translated -- the Destination IP was left un touched (of the outbound packet). There are times, however, when you need to translate both the Source and Destination, and those situations are what is called a Twice NAT.
To be clear, a Twice NAT is simply one of the four types of translations we've already discussed (Static NAT, Static PAT, Dynamic PAT, Dynamic NAT) applied to both the Source and Destination of a packet. A Twice NAT is sometimes referred to as a Double NAT (among other names).
Typically, a Twice NAT is configured using a Policy NAT, so make sure you watch that video for a clear illustration of Policy NAT.

You are most welcome =)

[@dennist.8018]

i have to come back and rewatch again to wrap my mind around, great video's though.

[@PracticalNetworking]

Thank you, Dennis. =)

You're welcome, Hamza. Glad I could save you time =)

Suggestions: each video for different VPN protocols , pros cons etc
Additionally, you can make server setup tutorials in Linux for different VPN protocols, proxy servers etc.

[@PracticalNetworking]

Thanks for the suggestions. The VPN one would be fun.
Linux is not my domain of expertise though, so I'm probably not the best for those.

[@NeurosesGamer]

Your videos are cathartic at this point Ed 😂

@@PracticalNetworking Hey Ed, I voted for your blog on Cisco's website. I actually feel you are worth a lot more than we can give. You have been there for our community. By the way, I flooded my network with requests to do the same. I pray you to win.
