Leak case study 4: Leaks If VPN server Can Not be Attained

A VPN’s security of an individual’s privacy and safety is dependent upon its being able to send all traffic through an encrypted channel to the affiliated VPN servers. When a VPN program has difficulty reaching the host it’s linked to, it might fail to correctly respond in a way that protect a user’s internet activity. This case study from our Privacy Research Lab clarifies these kinds of leaks, and also how to check for them utilizing the ExpressVPN Leak Testing Tools.

VPN server reachability summary

Occasionally, VPN software could be not able to achieve the VPN推薦 server which they’re connected to. This can happen for a number of reasons, for example:

  • Maintenance work, e.g. for essential software patches
  • Blocking
  • Hardware Evidence
  • Data center outages
  • Bad paths

While this occurs, an individual connected to this VPN will eliminate network connectivity. VPN software should observe this matter relatively fast and do it to renew the consumer’s connection.


These escapes should be looked at rather severe, since there’s a high likelihood of a VPN program being not able to achieve a host at any point in time. In the actual world, the likelihood of those issues occuring is comparatively significant. VPN providers must ensure not only their software not flow under these circumstances, but also that the consumer is rapidly re-connected into a reachable server. The latter point, however, is an individual experience issue and beyond the scope of this leak case research.

Reachability escapes

When the VPN server is unreachable, VPN software may behave in one of many manners:

  • Fail to See the problem, leaving the consumer with no network link
  • Detect the Problem, and disconnect the user in the VPN eternally
  • Detect the problem, and try to join the consumer to a different VPN server

In all these situations, a VPN program could flow.

Testing for leaks

Manual analyzing

Manually testing for leaks in such a circumstance is rather tough. In general you’ll not have any control over the VPN server and thus can not readily simulate a reachability problem.

Normally the best way to simulate a reachability problem is using firewalls. This may be done either using firewalls on the evaluation apparatus itself or firewalls within an apparatus, e.g. a router or virtual server host. We thus look at these measures appropriate just for electricity users to try.

Manipulating Firewalls

We provide breeding measures under that presume that the consumer is knowledgeable about firewall manipulation. To Be Able to control firewalls, we urge these tools:

Windows: Netsh Advfirewall

MacOS: Packet Filter

Linux: iptables


Repro Steps

  • Connect your device to the VPN
  • Determine the VPN server’s IP address
  • Initiate packet capture on all ports, e.g. using tcpdump
  • Create a firewall rule to block all incoming traffic to the VPN server IP
  • Wait for your VPN program to Observe the block and then stabilize to a new country
  • Stop packet catch
  • Remove the firewall rule
  • Disconnect the VPN
  • Check the visitors catch for packets which went unencrypted from the apparatus
  • Notice: Checking traffic catch may be tricky as there could be sound made from local IP visitors, ARP and other traffic that is acceptable.

Testing with the ExpressVPN Leak Testing Tools

The ExpressVPN Leak Testing Tools are an extensible package of accessible Python software made for both manual and automatic flow testing of VPN software. Please visit our introduction into the tools for directions on downloading and setting up the resources.

As Soon as You’ve set up the resources, Make Certain You are in the resources root directory and then execute:

These evaluations will execute precisely the manual testing measures described previously. They’ll ascertain the IP of the VPN server and make firewall rules to block connectivity to the VPN server. This may simulate a reachability failure.

The evaluations will subsequently track leaks for a time period to view how the VPN server responds. They check for a variety of forms of escapes and report any difficulties.
