Trust Local networks setting

First I know I can upgrade to NAV2009, but at this time I prefer not to. I do have a question about settings In NAV2008. I may have posted this before, but it was when all those yahoos came on and messed everything up

 

I have 1 desktop PC that is connected to the DSL box by the ethernet cable. The DSL box connects to the telephone outlet in the wall

at this time I have no router

 

So in NAV2008 settings

AntiVirus Options

  Realtime protection tab

     Internet worm Protection

       "How to stay protected from certain internet worm attacks"

            option "Trust local networks" box is NOT checked (thus I'm not trusting local networks)

 

But my question is

1.what is defined as the local network?

 

2. I know that if I had 2 or more computers, the network would be those comptuers. Since I have only 1 computer, does this setting refer to local network as MY Internet Service Provider? And thus all the computers that are part of my ISP?

 

3. If I CHECK trust local networks will that allow all users who have the same ISP as I to have access to my computer?

 

4.Or would it just mean that my ISP would have access to my computer?

 

I notice that when it is unchecked and I boot up, I seem to show a connection to an address in the range from my ISP that is different than the assigned IP given to me.

When I have trust checked, there are no such entries in my activity log

 

 

 

Just trying to understand, so that I can make the right choices

Since you have only one computer, there is no need to trust local networks.  You should also ensure that Computer discovery is Disabled in the trust settings.  Most computers have NIC cards that may allow you to find other  networks in the neighborhood.  Obviously, you want to close off any avenue for unsolicited access.

would it find my computer connection even if I'm not wireless? How do I  ensure that Computer discovery is Disabled in the trust settings. I Have NAV2008

If your network trust settings are the same as NIS, it should be in the network screen, on the left side panel near the bottom.  If you aren't networked, perhaps it doesn't show.  Since you aren't, leave your trust disabled. Other computer networks  won't be able to sense you, but you might be able to sense them. Your computer probably has wireless reception capabilities.  Most newer ones do.

I have NAV2008 would that setting be on there too? Where is it located?

 

I checked my netwrork in the NAV2008 panel and it only shows my desktop

Sounds to me exactly what you are supposed to see.  It’s a non issue.

Thansk Del- I agree that my set up looks like. But I still have a quation(s) about how the NAV2008 defines "local network" so my

questions still are

 

1.what is defined as the local network by NAV2008?

 

2. I know that if I had 2 or more computers, the network would be those comptuers. Since I have only 1 computer, does this setting refer to local network as MY Internet Service Provider? And thus all the computers that are part of my ISP?

 

3. If I CHECK trust local networks will that allow all users who have the same ISP as I to have access to my computer?

 

4.Or would it just mean that my ISP would have access to my computer?

 

I notice that when it is unchecked and I boot up, I seem to show a connection to an address in the range from my ISP that is different than the assigned IP given to me.

When I have trust checked, there are no such entries in my activity log

1.   Local network - home network

 

2.   No

 

3.   Not likely but it should be set to not-trusted.  Why would you do it any differently????

 

4.   Your ISP has a different address than you do which is why it shows a different address from you when it connects.

      If you have more than one computer, they each have different addresses.  The modem has an address, your ISP has an 

      address. 

 

Your ISP has access through the firewall rules.  If it can't get through the firewall you won't have a connection.

Hi,

 

You typically only want to trust your "local network" if it's a non-routable address, belongs in the private IPv4 address range, and if you want to have cross-communications between multiple computers on your "local network" (ie: sharing files/printers, etc...).  A "local network" for home users is typically defined to mean a class C ip address range.  (ie: for Linksys routers, 192.168.1.1 with subnet mask 255.255.255.0)

 

Many DSL boxes have built-in NATs so you may not see your WAN IP address from your computer.

 

I'd suggest that you leave the box unchecked if you do not have any other devices on your network.
