Thanks for your comment. Yes, I realise that using two firewalls could produce conflict. I prefer Zone Alarm to the Norton firewall included in the Security Suite and have grown to trust it through several upgrades. Since cannot seem to get ZA5.1 to work in the perfect way that ZA4.5 did (no matter how I try) so it is either stay with 4.5 version or revert to the Norton firewall.

Perhaps I should try again with a clean install.
