Do I need a firewall in my virtual OS
 

Greetings:

I have a primary os winxp and virtualbox with linux as guest and win2000.

1.Do I need to install each with firewall/antivirus in my virtualbox guest os'es.
2.Lets say, in my primary os winxp and If I block some ports, does my virtualbox guest os ports will be affected too?

no, I think they run individual.

Pls elaborate
 

Greetings:


Can anyone elaborate his answer. I dont understand.

thnx

Hi,

Each of the guest run on the WinXP via the VirtualBox. The WinXP should either have the firewall or a firewall via your modem/router. The ports for the guest are virtualized by the host.

If your VM machines are behind your router, then the router would act as a firewall (if configured) to all computers behind them.

But the three OS involved here will have separate IP's ie 192.168.0.1/2/3.

Each computer will be responsible for its own intrusion beyond the router.

For the Linux box you could use a program such as firestarter to configure your firewall. ( http://www.kylecorey.ca/?q=node/46 firestarter info)

On your 2000 machine you will definately want virus protection of some sort. You could also install a 3rd party firewall there too.

Hope that helps.

Kyle. (Please anyone correct me if I am wrong)

Sorry of my English.
Caighil is right, even though the OS's behind the router and run under vmware. But each have their own ip-addr. Therefore, each OS's will have charge to get attack.
So, you need some kind of protection for each OS.

Hi,

I beg to differ here. If you have a decent firewall for the router/modem and most do. Then you are just putting up additional protection, in my thought excess. Paranoia can be good at times but overkill in other times. People tend to think more is better.
Why add the overhead?

Define decent router.

A 49 dollar linksys, yes it can protect computers behind it if configured, but it is not a 1000 dollar cisco router (yes that would be overkill :) )

But Virus protection sort of falls under a different category, and each windows computer should have its own imo.

Again onebuck is right, the router probably has traffic control capabilities, but you would have to configure it to see if it meets your needs.
