### IIS HTTP Binding Microsoft IIS will automatically be configured for security to operate with the Kaseya Application Firewall When installing R94, Kaseya will automatically configure Microsoft IIS to listen on port 18081. This will overwrite any existing IIS configurations and IIS will only operate as the web GUI for the Kaseya applications. If you have other websites installed on IIS, they will not function after installing R94. R94 Installs the Kaseya Application Firewall (KAF) which will terminate all incoming/outgoing web traffic in order to provide a deeper level of security to mitigate application security attacks. As such, KAF will handle all web traffic on port 80 and 443 and, after inspecting it, pass it internally to IIS on port 18081. Installing the Kaseya Server changes the default IIS `http` port binding from 80 to 18081. It also removes other bindings that might be already specified, such as `net.tcp`, `net.pipe`, `net.msmq`, and `msmq.formatname` Click the Fix it link next to this missing prerequisite to have Kaseya Server Setup fix it for you. Note: See IIS Port Check and SQL: SSRS Port for related port configurations.
