No internet access unless firewall turned off

running ISS2009, XP SP3. use sierra AT&T wireless broadband card. after installing, IE 7 will not connect (DNS error), Outlook will not connect to e-mail server. i have set program permissions all to allow, ISP IP range for AT&T to trust. nothing works. if i turn firewall off (like now), i can conduct business as usual. i turn windows firewall off when i turn the McAfee firewall on abd vice versa.

did not have this problem with norton.
