Firewall blocks ICS (Internet connection sharing)

Hello!

I have two lap-tops:

1. "Host" laptop (Vista) connected to the Internet via wired LAN with Total Protection installed

2. "Guest" laptop (Win7) with Total Protecton installed

I create a wifi ad-hoc connection between those computers (manually giving 192.168.0.xx -style IPs) and enable ICS on the LAN connection of the 1st laptop.

The network is established fine but has no internet connectivity (although Win7 Network and sharing center on the 2nd laptop says it has internet access) - applications can't reach internet.

When I disable firewall on the 1st laptop everything works just fine, programms on the second have internet access.

IP of the 2nd laptop is added in My Network Connections with security level "Home" in the firewall settings.

Please advise me what can I try to resolve this.

Thank you in advance.

Have you enabled ICS ports from Firewall settings?

Thank you for your answer.

No, I did't open ICS ports. I tried opening all the ports firewall has to offer and it didn't help. Should I add those ports manually? If so, what are their numbers?

Thank you.

I´ve tried to do the same, but with IPAD. Same problem, when the firewall is turned-off everthing works fine.

I think we find a bug.

It will be good if you contact our technical support and allow them to remotely access your computer to fix this issue.

Re: Firewall blocks ICS (Internet connection sharing)

I made that yesterday, and they said that it is not possible and that they have tried everything. I said that this is not a solution and they should take  the problem on mcafee engeneerings, they told me to ask for apple about the problem, but is obvious that is not a apple problem. If it was, even i turning firewall off it will not works and happens the opposity.

There is something wrong with the mcafee firewall, something is blocking the connection betwwen device and computer even if you disable all configuration on firewall.

By the way the support said that I should use it with firewall disable, but you will agree with me that this isn't a solution also.

MAYBE, they will call me today, if it happens i'll post something more.

Re: Firewall blocks ICS (Internet connection sharing)

Hi,

i'm having the same problem. I'm using a windows 7 ultimate laptop and try to share the internet connection using the built-in ICS featue. It all works well as long as McAfee firewall is turned off.

Any idea how to adjust the firewall setting to make it work?

Thank you in advance for your speedy answer,
