How is the proxy server setup? Do you have to configure the browser to use it? What browser are you using? Have you configured the IE proxy settings via a policy? Can you make an exception on your firewall rule to permit traffic to McAfee? – Zoredache Jan 5 '11 at 19:11

You can configure the proxy (and maybe firewall) to allow the connection to McAfee site.

This FAQ from 2007 says it is possible if you do not require a username and password to use the proxy, but you have to install a patch downloaded from there. This thread from early 2009 also points to that patch, but says that authentication support was being planned for 2010.

Now that it's 2011, I do not know if this is out of date.

you can try the following rule into your file.

iptables -I INPUT -s -j ACCEPT iptables -I PREROUTING -t nat -s -j ACCEPT

change to your pc ip.
