I have a wireless laptop running Vista Home Premium which has numerous packets blocked by the Checkpoint firewall with the message "TCP sequence number is lower than ISN". Any ideas on what I can do to fix this? Thanks.

Hi, You need to adjust settings on the firewall to allow the blocked programs. Please contact Checkpoint support or related forum for more information. https://supportcenter.checkpoint.com/supportcenter/portal/user/anon/page/default.psml/media-type/html?action=portlets.SearchResultMainAction&eventSubmit_doQuicklinks=&quicklink=Forums Important Note: Microsoft provides third-party contact information to help you find technical support.
