Firewall clients cannot authenticate to the web proxy service. You have two choices: 1. quite trying to control web proxy access with firewall clients 2. set your HTTP Redirector to "forward to requested server" or "disabled" Jim Harrison MCP(NT4, W2K), A+, Network+, PCG http://isaserver.org/Jim_Harrison/ http://isatools.org Read the help / books / articles!
