Summary<\/h2>\n

Since installing 21.0-20241023-nightly, apps on my tablet can no longer access Internet when Wireguard is connected. This worked just fine right up until 20241023-nightly, and Wireguard’s app hasn’t been updated in over a year, so I’m pretty sure it’s the new build.<\/p>\n

Looks like it’s DNS. (It’s always DNS.) There are a couple of conspicuously related-looking commits in this build: 406071<\/a> (VPN-covered DNS traffic may not fall through) and 406070<\/a> (Revert ”Prevent DNS traffic from bypassing lockdown VPNs”).<\/p>\n

Expected Behavior<\/h2>\n

Apps should be able to connect to the Internet even when Wireguard is connected.<\/p>\n

Current Behavior<\/h2>\n

Apps lose access to Internet immediately when Wireguard is connected. Curiously, Chrome is unaffected; all other apps that I’ve tested are affected, including Firefox, which says ”Address not found”, hinting at DNS.<\/p>\n

Steps to Reproduce<\/h2>\n
    \n
  1. Install Wireguard<\/a><\/li>\n
  2. Set up a connection that doesn’t route all traffic but just that interface’s address space. I’m including a screenshot of my Wireguard configuration below.<\/li>\n
  3. Toggle the Wireguard interface on.<\/li>\n
  4. Open Firefox and try to browse the web.<\/li>\n<\/ol>\n
