Just the opposite week, ExpressVPN, one of many business main VPN companies, had to take its split-tunneling feature down for Windows users due to a DNS leak issue. The downside is believed to have first begun with model 12.23.1 method again in May of 2022, however wasn’t observed till not too long ago.

While the DNS leaks had been confirmed by ExpressVPN, it was believed to be a comparatively small variety of customers, round 1 %,  who had been affected.

Windows customers can breathe a sigh of aid although, as in response to ExpressVPN the problem has now been resolved. Split-tunneling is as soon as once more accessible to Windows customers after the service’s engineering staff was capable of establish and repair the problem.

According to an in-depth blog post on the corporate’s web site, the issue was dominated to not be a results of exterior elements however apparently attributable to two separate inside points. 

ExpressVPN acknowledged, “The first issue was introduced when we built our split-tunneling feature for Version 12 of the ExpressVPN Windows app (this issue was never present in Version 10). In every instance, the DNS cache service should have been automatically directed to use the VPN. However, when split tunneling was activated in “Only allow selected apps to use the VPN” mode, the DNS cache service was allowed to function exterior the VPN, which meant that some DNS requests could be misdirected.”

“The second issue was caused by the presence of other VPN apps on a Windows device. When other VPN apps were installed, even if they were not in active use, it was possible for their filtering rules to affect the performance of our app. This cross-contamination only occurred when split tunneling was turned on. We improved the filtering logic to eliminate potential DNS leaks with split tunneling.”

After intensive in-house testing, ExpressVPN has launched two up to date variations, Version 12.74.0 and Version 10.51.0 with the bug fixes. It is beneficial that every one Windows customers replace these apps as quickly as potential.
