A VPN (Virtual Private Network) functions as a private tunnel through the internet which encrypts your data and secures your connection when using public Wi-Fi connections such as those in cafes or airports.

Does Avast have any suggested practices for accommodating this behaviour when using a firewall? I assume that amenability to firewall accommodation is a consideration in application design these days (though I could be wrong). Firewall included in Avast Internet Security and Avast Premier creates rules each time an application or process starts for the first time. These rules determine how Firewall behaves toward each application or process when it connects to the internet or to another network. On the off chance that a port is designed as a protected port and the most extreme number of secure MAC locations is arrived at, when the MAC location of a workstation endeavoring to get to the port is not quite the same as any of the recognized secure MAC addresses, a security infringement happens. 12 ways to boost your router's security With the increasing number of network security breaches, we need to improve awareness regarding the security of your home network.

Troubleshooting

How can I prevent the WebRTC leak on my browser?

WebRTC is a feature that various browsers such as Google Chrome and Mozilla Firefox apply because it supports B2B applications such as voice calling, video chat, and P2P file sharing without the need for plugins. In Windows, macOS, and Android systems, this feature potentially enables IP addresses to be visible even when you are connected to a VPN such as Avast SecureLine VPN.

We are actively looking for a solution to this issue. In the meantime, protect your privacy by blocking or disabling WebRTC. You can also avoid this vulnerability by using a browser which does not apply WebRTC (such as Safari or Internet Explorer).

For more details, refer to the following article:

Why can't I browse the internet when I connect to SecureLine VPN on Windows?

If you can't browse the internet while connected to SecureLine, try the following solutions (for Windows systems only):

  • Check the signal strength of your Wi-Fi. Some hotels or hotspots have weak Wi-Fi signals.
  • Verify that you have accepted the Terms and Conditions of the Wi-Fi hotspot provider. To do so, open your browser and, if prompted, accept the terms of the provider to connect.
  • Try using a different browser.
  • Ensure that your DNS resolver is working properly (in Windows 8 or later). To do so, disable the smart multi-homed name resolution service by following the instructions in the article below:

What should I do if SecureLine is unable to establish a connection?

If SecureLine VPN is unable to establish a connection, try the following solutions:

  • Check if your internet connection works without SecureLine. Disconnect SecureLine and try to browse the web. If the internet connection still doesn't work, check your network configuration.
  • Select a different SecureLine VPN location.
  • Disconnect other VPN services that may be running on your PC. If you are connected to another VPN, it is likely that SecureLine won't work properly.
  • Restart your PC and try to connect to SecureLine VPN again.
  • Check the configuration of your firewall. Firewall configurations vary according to the vendor/manufacturer; consult the related documentation for information about running a VPN.
  • Confirm that your SecureLine subscription is active. In Avast Antivirus, go to ☰Menu ▸ My licenses, then scroll down to the SecureLine VPN section.
  • Some routers have the option to enable or disable IPsec, sometimes displayed as VPN passthrough. For SecureLine VPN to connect and function properly, ensure that IPsec or VPN passthrough is enabled.
  • Consult your firewall vendor to check that UDP port 500 and UDP port 4500 are open on your firewall.

If SecureLine VPN is still unable to establish a connection, try to uninstall and re-install the software.

What should I do if the text 'Content not available' appears in the application window?

If the message Content not available appears in the SecureLine VPN window, try the following solutions (for Windows systems only):

  • Go to Privacy ▸ SecureLine VPN to reload the page.
  • Disconnect other VPN services that may be running on your PC. If you are connected to another VPN, it is likely that SecureLine VPN won't work properly.
  • Restart your PC.

Why did I receive the error message 'SecureLine has encountered a technical issue'?

If the SecureLine VPN interface becomes empty apart from the error message SecureLine has encountered a technical issue, try the following solutions (for Windows systems only):

  • Check if your internet connection works without SecureLine. Disconnect SecureLine and try to browse the web. If the internet connection still doesn't work, check your network configuration.
  • Restart your PC.

If this solution does not work, try to uninstall and re-install the software.

Miscellaneous

When is the regularly scheduled maintenance?

Regular maintenance occurs every Saturday at 6PM EST (GMT/UTC -5), or 6PM EDT (GMT/UTC -4) during daylight saving time, and lasts for one hour. Your service is not typically affected by this maintenance.

Why do Gmail and Live Mail send me suspicious activity alerts when I'm connected to SecureLine VPN?

If you use a different location when you connect to the internet via SecureLine VPN, Gmail and Live Mail may detect this change. You may receive an email reporting suspicious activity, and will be asked to change your password if you think someone in a different location has accessed your email. Verify the VPN location you selected to ensure your security.

Why do certain websites claim that I'm connected to a different city than the city I selected as my VPN location?

Websites often attempt to identify the location of their visitors from their IP address, a process called IP geolocation. IP geolocation uses a database that pairs together IP address ranges and geographical information. The information in this database can be inaccurate for several reasons:

  • Avast does its best to provide accurate information to the IP geolocation databases, but the database providers may take extra time to update the location.
  • The website may be using an outdated version of the geolocation database.
  • Some major websites (Google, for example) maintain their own databases based on what user traffic came from the IP address in the past.
  • In certain locations, we rent dedicated servers to provide SecureLine VPN, and the IP geolocation databases are updated by the server provider on Avast's behalf. Because Avast is a Czech company, these providers may indicate the location as Czech Republic. When this occurs, we work with the providers to update the information with the correct locations of our servers.

Why is SecureLine VPN a paid product when other VPN services are free?

To support the continued development of SecureLine VPN and give you access to the best VPN technology, SecureLine VPN is a paid product.
