FIRESTARTER Firewall


Recommended Posts

FIRESTARTER

 

shot1.jpg

 

Okay Guys this is the Program that I'm using with Fedora Core 3 (on a Dual Pent 3 1GHz server -1Gb Ram)

 

The Server has 2 Etho Cards and Eth0 is DSL Eth Modem!

 

My network consists of 4 permanent Windows XP SP2 machines (and upto 30 Various operating Systems on the occasional LAN Parties)

 

MY problem is That whislt Gaming (Soldier Of Fortune - II - Double Helix) on one of the Windows Machines the game will lag for a second or two every 15 seconds ???

 

This does not happen when the server (Dual BOOT) boots into Windows XP as the SERVER??

 

Any IDEAS?? is it this Firewall program? (or is it a possible service? set up by default in FED3 ?) is there a better way of FireWalling AND enabling Internet connection sharing? (which firestarter does)

a simple test would be to disable the firewall and see does the issue go away, if so then aat least you know where to start pointing the finger at

 

that said, i had a similar issue a few years ago with quake 3, and about 5 reinstalls of windows xp later i figured it out, nothing wrong with the os, but my firewire card was causing the issue, disabling it in device manager and i havnt seen the problem since

 

cheers

Thanks guys

 

Yeah has me beat runs fine exact same sys in wnidows BUT boot into Fed3 and NFG :(

 

I used FireStarter Primarily as an easy way to enable Internet connection sharing because it was a part of the proggy :P

 

Any other programes you might suggest for firewalling and/or connection sharing ?

 

I know I've gotta read your IpTables sect. :blink: but I was looking for a "quick fix" :huh:

 

Will have to learn to do things the right way even if it takes a little more effort ;)

 

 

"dmesg" ?? never hear of it >LOL< will have to try next time in FED :P

Hi there,

 

Avoid running firestarter as an application and/or in the systray, as it is a resource intensive application. you can run fs as a service (service firestarter restart) so it's all run in the background.

 

of course if this is what you are doing... then I don't know what the issue is... maybe a hardware issue?

 

as for dmesg... cat /var/log/dmesg or type dmesg... it will show you all that cool stuff that linux (used to) show you when you boot up.

 

da!!as
