For Sygate Firewall, use this configuration, posted by someone earlier:
So, I opened Sygate, went to tool/options/security and found that "enable
stealth mode browsing" was checked. I unchecked it, enabled Sygate and
disabled XP firewall and the rest is history. I'm able to use the windows
update (IE - tools/windows update).
