I was looking at the content in my ZoneAlarm zones, and I noticed 'loopback adapter' is listed under the trusted zone...the only thing not listed in the internet zone. I've never noticed it, but it sounds pretty harmless. I don't know much about firewalls or zones...can someone tell me whether loopback adapter should be in the trusted zone?

"Loopback is used for testing or debugging problems. Loopback simply means that data sent out will be delivered back to the source (usually without actually going across a network)."

So...is the loopback adapter a part of the firewall...is it something every computer has, or what? I looked up the term, but I have no idea what all the technical jargon means.

Is isn't any kind of spyware aid, is it?

The Loopback Adapter is a tool to create a virtual network. This allows you to configure your network settings prior to connecting to the network. If you are not using your system and or have no plans to use it on a network, you may disable it. Otherwise I see no harm in leaving it.

I'm not connected to a network...so why do I have a loopback adapter? Does every computer have it?

It is a feature within the control panel of the OS. And I'm guessing here, but I'm thinking it may have been inadvertently turned on. And I would have no idea how that could have been done. I wish I could answer that, but in all honesty, I'd just be guessing.

I think you have 98 right? Go to the Control Panel and double click the Network Properties. Do you have VPN or Virtual Private Networking in there?

How do you connect to the internet and who is your ISP?

Yep, Windows 98.

I went to 'Network' (didn't see 'Network Properties')...I saw 'Microsoft Virtual Private Networking Adapter'. Also, 'NDISWAN -> Microsoft Virtual Private Networking Adapter', and 'Dial-Up Adapter #2 (VPN Support)'.

Might sound strange, but I'm not quite sure how I connect...I know not by dial-up. It's high speed provided by Charter Communications...I'm not sure of the differences between cable, DSL, modem...etc etc.

My sources tell me Charter is a cable internet provider. You don't have any need for those VPN entries but they are not doing any harm either. You can remove them or leave them, its up to you. If ZA is blocking it there is no harm being done. You can remove the Loopback Adapter from ZA if you want also.

I am also showing the Loopback Adapter in ZoneAlarm, both the Pro version on my XP-Pro computer and the free version on my 98SE computer. I have a simple network with 4 computers hooked up through a LinkSys router. I did not have the Loopback Adapter showing up in Zone Alarm on my 98SE computer until I upgraded to ZoneAlarm Free version 6.0.667.000. I also have ZA Pro version 6.0.667.000 on my XP system. I do not have VPN installed on either system. This entry in ZA did not show up until I installed version 6.0.667.000. I'm thinking something is going on in ZA's newest version.

Thanks, Leurgy. I will remove the entries...I don't know if ZoneAlarm is 'blocking' them or not. I think I'll remove loopback adapter also...it wasn't there before I installed the new ZoneAlarm.
