I am a Linux Newbie (but Windows veteran). I am trying out the SuSE SLED 10 (Eval) in dual boot mode with Windows XP (SP-2). I am connected to Internet through an external ADSL modem, which is connected to my PC through an Ethernet cable.
While setting the firewall (through YAsT), I cannot decide which mode to set.
I referred to some commercial books on SuSE. The book describes a firewall that needs to run on a separate machine; to protect PCs/servers on a LAN.
For example, it says that the firewall has three interfaces:
1. "Internet" (connected to Internet)
2. "Internal network" (All PCs on the LAN)
3. "De-Militarized Zone" (DMZ)-- For servers (FTP, Web server, etc)
I checked the forum about this, and the thread http://www.linuxquestions.org/questi...d.php?t=411432
says that this is meant for a computer with 3 network cards.
But this makes sense only if I have another machine to run the firewall. But that's not the case here: I only want the firewall protection for my home PC.
Secondly, although the book describes three separate connections that exist simultaneously, my GUI provides all of them from a single pull-down menu, which implies that I can select only ONE of the options. This is confusing!
Thirdly, the pull-down menu of the Firewall GUI does not have a "personal firewall" option, where there is only one outgoing connection (to the ADSL modem).
What should I do?
Thanks in advance!
