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 http://video.google.com/videoplay?docid=-1065159392607021977 The slides in PDF format: http://www.haifux.org/lectures/70/ipmasq-lecture.pdf Eli ----------------------------------------- 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. -- Web: http://www.billauer.co.il _______________________________________________ Haifux mailing list Haifux@haifux.org http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux
