Subject: [Haifux] IP Masquerading lecture uploaded to Google Video
 
Hello all.


Almost exactly five years ago, I gave my IP Masquerading lecture, which 
showed the fundamentals and hands-on of getting several computers to 
share an ADSL/cable modem connection (plus a bit about firewalling).


The lecture was recorded on video at the time. I've recently uploaded a 
slightly edited version of that lecture to Google video.


As far as I can see, it's hasn't lost any relevance since (except for 
the ipchains part). The slides are in English, but I speak Hebrew on the 
video.


So if anyone is interested, it's at

Below: A copy of the original invitation to the lecture:



IP masquerading is a technique of manipulating IP packets, which makes 
it possible for computers to "hide themselves" behind IP addresses that 
they don't actually own. I suppose that the most popular application of 
this is sharing an IP number between more than one computer.

Or in practice: Having a single ADSL (or cable) connection shared 
between several, possibly non-Linux computers. It turns out to be quite 
easy to get it working well. If you know what you're doing, that is.

The lecture will deal with how iptables works in general, and emphasize 
the subject of masquerading (or NAT, to be accurate). The aim is to 
understand the mechanism of iptables, and how IP packets are going 
through it. Example commands for setting up both a firewall and IP 
masquerading will be shown and discussed.

I will also discuss how to fake the address of your ISP's DNS, so you 
can configure a static address on the local computers, even if the real 
address isn't static.
