Hi, Please I need your help in what should I do to solve the following error message when publishing a website: FWX_E_TCP_NOT_SYN_PACKET_DROPPED 0xC0040017 A non-SYN packet was dropped because it was sent by a source that does not have an established connection with the ISA Server computer. The website publishing rule has the following settings: - Forward the original host header instead of the actual one: Not selected, as it's a regular website that doesn't require to have the client's IP. - Requests appear to come from the original client: Not selected, and the ISA is natting the traffic not routing it. - The security on the published website is set to anonymous. - The weblistener is not set to authenticate. - The hardware firewall interface after the ISA is set to route mode. - When I try to access the website from outside it says: Forbidden (403) You were denied access because: Access denied by access control list. And the ISA log gives the error message above, the public IP is directly mapped to the listener on the ISA server, I followed the following document: http://www.microsoft.com/technet/prodtechnol/isa/2004/plan/publishingweb servers.mspx Thanks r.
