Of course, the configuration file can be further customized through the app’s main window. If you are not certain where you should start, run the IceFloor Configuration Wizard and specify which inbound and outbound connections are allowed. The IceFloor main window is separated into multiple tabs, and by navigating between them you can easily set up firewall rules for inbound and outbound connections, create various presets, manage hidden services, create custom rules, and much more. Provides quick access to a wide range of customization options for the PF firewall Usually, these adjustments can be performed via the Terminal, but IceFloor enables you to quickly establish your own rules and create configuration files with just a few mouse clicks. IceFloor is a Mac OS X application that provides an user friendly graphical interface for the PF firewall, in order to offer a more extensive control over your traffic. User friendly workflow for personalizing your PF firewall settings The first one is able to protect you against unauthorized apps or services that try to accept incoming connections, and you can easily customize its behavior via the System Preferences. P.S.Mac OS X comes with two built-in firewalls: ALF, for the applications, and PF for the network. Īnd we can continue using Charles for debugging with IceFloor turned on. To see if limit works for me, I usually go to. Hit "Apply" every time you change any setting. If you need those as well as bandwidth control, NLC in step 3 is what I would use (or if you use HTTP as a protocol, Charles also can do this).Ĭlick "Start PF" and you are good to go. Note, that we can't specify packet drop rate or latency here. And here is the thing we've been chasing - Max. Last step, Firewall tab, select "Outbound (NAT clients)" list, add required protocols to "Services in selected Address Group" (I just added "All services"). Now to NAT tab, check "Share internet connection" and select interfaces that you located on previous screen. In IceFloor navigate to Interfaces tab, click Update button and locate Ethernet and bridge interfaces. Make sure it works, browse some page or stream video from your app. " IceFloor is a graphic frontend for PF".įirst we go through step 3 above: connect Ethernet, turn on Internet Sharing, connect our device to shared WiFi. Since I might need to use RTP (or smth not HTTP) in future, let's take one more step. Keep in mind that free version shows "waiting popups" occasionally and restarts every 30 minutes. You can also set breakpoints on everything. Lets you throttle specific host accessed with HTTP(S). NLC also able to simulate packet drops and latency. This is the easiest way, if you don't mind all your connections on both laptop and smartphone slowed down. If you have laptop (or desktop with WiFi interface), connect to network via Ethernet, setup Internet Sharing from Ethernet to WiFi, connect device to shared WiFi and use Network Link Conditioner on Mac or similar software which is easy and straightforward but can only limit all connections together. Besides, with some models you'd need to restart router every time you want to turn on/off throttling.ģ. Throttle bandwidth on WiFi router, if it supports such a feature.Īnd everybody connected to the same router will suffer. Not an option, cause I need clean stock firmware on device.ģ. Root phone, install or hack your own application which will limit bandwidth (or play with iptables) I need to be able to do the same thing on real device as well, so strike off.Ģ. iPhone has this feature built in since iOS6.Īs I use Mac OS, I will list instructions for it. The other day I needed to throttle (limit bandwidth) of video streaming application on Android for testing purposes.
