Hi, I have NTLM authentication set on the ISA firewall rules for specific IP ranges. I am getting shouted at by developers and people using specific apps because the proxy is not allowing them to authenticate through – or more correctly, the application isn’t allowing it through. These are most often PHP developers using various PHP based applications etc. I have created a rule which excludes specific IP addresses from authentication, which is working, but more and more people are now requesting this. I wanted this initially for the Websense logging system – but is there any other way round this? Thanks.
