I have a question that has cropped up recently. I have a gamesystem =
with an ethernet card in it. My old setup had everything going thru my =
linux system to the internet. The linux box has a DHCP and caching DNS =
server running and it all seemed to work great. I have had this setup =
since December of 2000 and have had to make little modifications to it. =
Unfortunately, my PS2(the above game system) does not seem to like this =
very much. The issue is unfortunately port forwarding. To fix this(on =
a temporary basis) I used the router portion of my hub(its a linksys =
cable/DSL router that I bought a few years back on the hopes that it =
would work better or at least as well as the linux in routing, and save =
me a few bucks on power. Unfortunately back then, it failed miserably. =
However, recently with my current problems, I was reading that the thing =
is upgradable by firmware. I did that and it works better. Rather than =
fail after a few hrs of operation, it lasted about a week before =
requiring powercycling. My problem is more software and comes from the =
fact that game makers for PS2 don't seem very communicative about what =
ports need to be opened in their software for stuff to function =
properly. The linksys router supports a DMZ host which throws the PS2 =
system on the network unprotected. My question is, is there a way to do =
this in software in the linux box? I know I could probably get 1 more =
hub, and put the exterior connections(the PS2 and the linux box) on it =
and get another IP from comcast. I don't want to do this for my whole =
network, and it comes from the fact that I never could convince my =
systems that they didn't need to go to the internet for local file =
xfers(which I do a lot.) So, does anyone have any idea how to simulate =
the DMZ portion of the linksys router under linux? Im running a 2.4 =
kernel(2.4.19 to be exact.) Oh, and I'm looking for something a bit =
cleaner than just forwarding every port to the PS2. =20
