When IP filtering is disabled, blocked internet traffic will be routed into the local VPN service, which will operate as a sinkhole (in effect dropping all blocked traffic) No, depending on the mode of operation basically one of two things will happen with your internet traffic: #(6) Will IGuard send my internet traffic to an external (VPN) server? This means that it might look like IGuard is using a lot of battery power, but that in fact the total battery usage of all apps is still the same.
#Iguard via android
Note that Android often incorrectly contribute battery usage of other apps to IGuard, because the network traffic of other apps is flowing through IGuard.
#Iguard via update
You can decrease the update frequency using the settings to reduce the battery usage. This is why the notification is shown only when the screen is on. The network speed graph notification will use extra battery power.
Generally the battery usage on older devices might be unacceptable, yet hardly noticeable on modern devices with an efficient processor. The battery usage when IP filtering is enabled depends on the quality of your Android VPN service implementation and the efficiency of the processor of your device. If IGuard uses a lot of battery power, please double check your settings. All settings resulting in extra battery usage, like IP filtering and logging, have a warning. #(4) Will IGuard use extra battery power?īy default IGuard will hardly use any battery power. No, the minimum required Android version is 5.1 (Lollipop) #(3) Can I use IGuard on any Android version? However, IGuard supports a SOCKS5 proxy to chain VPN applications. IGuard is a firewall application, so there is no intention to add VPN support. Android allows only one application at a time to use this service. If the VPN application is using the VPN service, then no, because IGuard needs to use this service. #(2) Can I use another VPN application while using IGuard To protect yourself more, remember to disable Wi-Fi and mobile data before rebooting, and only enable them on reboot, after the firewall service has started (and the key icon is visible in the status bar). On Android O do not enable 'Block connections without VPN', see question 51) for more information on this. However, this does not work properly on all Android versions/variants causing IGuard to hang and block all connections.Īndroid N and later allows IGuard to be an Always-On VPN. In the advanced options you can enable Seamless VPN handover on reload to prevent traffic from leaking when the Android VPN service is being restarted.
It will, however, be much better than nothing. Also, the Android VPN service needs to be restarted to apply new rules when connectivity has changed or when the screen is being turned on or off. The firewall can only start when Android "allows" it to start, so it will not offer protection during early boot-up (although you can disable your network before rebooting). This is the trade-off required to make a firewall which does not require root access. IGuard will do its best, but it is limited by the fact it must use the Android VPN service. No - nothing can completely protect your privacy. (1) Can IGuard completely protect my privacy? Depending on the theme you use, the icons may be:Īllowed (internet access permitted): greenish (teal) / blue / purple / grayīlocked (internet access denied): reddish (salmon) / orange / yellow / amber.You can use Settings > Defaults to change from block/blacklist mode (disable Block Wi-Fi and Block mobile, and then block unwanted applications in IGuard's applications list) to allow/whitelist mode (enable Block Wi-Fi and Block mobile, and then allow desired applications in IGuard's applications list). Enable the IGuard firewall using the switch in IGuard's action barĪllow (greenish*) or deny (reddish*) Wi-Fi or mobile internet access using the icons next to an application name in IGuard's applications list
