Hi,

I am thinking of dedicating an extra pc to FS9 multiplayer simming over the
internet. In order to get best performance, I am thinking of NOT installing
a firewall or antivirus program, unlike my current pc. Would I even notice
the difference in performance and would it be worth the trouble to run the
risk of getting infected by some virus?

TIA!

More about : firewall performance

Don't connect to the internet without a firewall. A hardware firewall may be your best solution if you want more
performance. You aren't going to see much. Maybe 1/2 or 1 full FPS at most.
If you decide to not run AV while flying don't forget to turn it back on anytime you go surfing. If you've set your AV
up to not scan your FS folders you aren't going to notice any perf gain.

Not worth the risk IMO, but I hate rebuilding machines.

Thanks for putting my problem in the right perspective. If I gain 1 FPS,
perhaps it wouldn't be worth the risk indeed. On the other hand, I've now
started the research on this subject, it cost me time already, then why not
complete the entire project...lol....
Thanks Carl!

Both of you thanks for the input.
I already have a router, for the homenetwork's connection to the internet.
Which means I actually have 2 firewalls...lol... I could turn of the
software firewall on my machine, that is, if I can trust my neighbours...

Be careful! A router is not the same as a firewall. Although a router
blocks all traffic from the Internet (unless allowed and forwarded to a
specific computer behind the router), it doesn't prevent
worms/virusses/mass-mailers etc from inside your network to access the
Internet.

Since your system runs solely FS there's little risk of getting infected
(unless you install add-ons obtained with online-sharing-software).
Don't forget other systems on your network could infect your FS-system,
so run AV software on them!

Cheers!

Actually most routers that I've used include a hardware firewall. Though your precaution is an excellent point to
check.

My Linksys BEFSX41 is claimed, by Linksys, to be a "Firewall router"
(it includes SPI and a few other "firewall like" features), though
when I read a news group like comp.security.firewalls, the regulars
there will never accept the idea that something like the "BEFSX41
router" is anything more than a glorified NAT router, and they will
only accept the definition of "hardware firewall" with respect to
units they call "Firewall appliances", like those offered by
WatchGuard and other such vendors. And of course, those people also
feel that "software firewalls" (Personal Firewalls) are useless as
well. I can understand many of their concerns, and can appreciate
the advantages of a full blown "firewall appliance", but defining
what is, or what is not, a "firewall" can be an endless semantic
discussion on various levels. :-)

I mentioned such a "router" device as being perhaps a reasonable
enough solution for HEnk, considering how he described what his plans
were, because I assumed an already "clean" system, with no other
potentially "vulnerable" programs (email, IRC, browsers, etc.)
running alongside fs9. If this were the case, no other programs
should be initiating outgoing connections, and without port
forwarding and such going on, the router should be enough to prevent
unsolicited incoming intrusions.

Well someone will correct me if they disagree, but routers are normally
natural firewalls. As if setup correctly and when your IP address is
under attack, they can indeed attack the routers ports, but can't get to
the your computer(s) ports. Since the router will not send them to the
computer(s). Thus nothing happens.

I run a 2Wire Home Portal 1000HG which is an ADSL modem, a wireless
router, and a hardware firewall all in one. Seems to be really securely
stable to me. While this isn't totally fool proof, anybody worried can
check out this website:

https://grc.com/x/ne.dll?bh0bkyd2

Then click on Proceed. The run all of the basic tests. If you pass with
a Stealth rating, a hacker will not even find anything using your IP
address. And this means unless your visit a malicious website or
something, There isn't anything a hacker can really do anyway. As to
them, you are totally invisible.


Cheers!

I agree with you that it is a reasonable solution. The discrepancy is most likely due to the fact that the security
guys are trying to lock down corporations with 100's even 1000's of users. In which case they are correct. For home
use though unless you have a really big family living with you Zone Alarm is fine except for the CPU resources needed.
You are pretty safe with the alternatives you discussed. I mean it just doesn't make sense to go out and buy a $30,000
hardware firewall to protect your PC that is used for web surfing, etc.

I got a perfect stealth rating again, I usually check about every 3 months.

That's a very good site for testing. I use a LinkSys BEFSR41 Cable/DSL
Router, and it is VERY secure:

Your Internet port 139 does not appear to exist!
One or more ports on this system are operating in FULL STEALTH MODE!
Standard Internet behavior requires port connection attempts to be answered
with a success or refusal response. Therefore, only an attempt to connect
to a nonexistent computer results in no response of either kind. But YOUR
computer has DELIBERATELY CHOSEN NOT TO RESPOND (that's very cool!) which
represents advanced computer and port stealthing capabilities. A machine
configured in this fashion is well hardened to Internet NetBIOS attack and
intrusion.

Unable to connect with NetBIOS to your computer.
All attempts to get any information from your computer have FAILED. (This
is very uncommon for a Windows networking-based PC.) Relative to
vulnerabilities from Windows networking, this computer appears to be VERY
SECURE since it is NOT exposing ANY of its internal NetBIOS networking
protocol over the Internet.
