Hi guys. Does n1 have n ideia how I can resolve theses 2 problems? Source: Microsoft ISA Server Web Proxy Event ID: 14148 Type: Warning Category: None Description: The Web Proxy filter failed to bind its socket to 192.168.10.254 port 8080. This may have been caused by another service that is already using the same port or by a network adapter that is not functional. To resolve this issue, restart the Microsoft Firewall service. The error code specified in the data area of the event properties indicates the cause of the failure. 192.162.168.10.254 it's internal IP from my ISA Server. All clients use these IP as default gateway. Wen I create a firewall rule to block access *.fotolog.net (example), my internal clients CAN access fotolog.net site.

How I can configure ISA Server to trust in this IP? Thanks guys!!!! Rafael Rodrigues.
