title: Server not reachable within a VPN (SNX) out of a Docker container
body: <p>I am working with the latest Manjaro with the kernel: x86_64 Linux 5.10.15-1-MANJARO.</p>
  <p>I am connected to my company network via VPN.
  For this I use SNX with the build version 800010003.</p>
  <p>When I start a Docker container (Docker version 20.10.3, build 48d30b5b32) which should connect to a machine from the company network, I get the following message.</p>
  <pre><b>[maurice@laptop</b><b> ~</b><b>]$</b> docker run --rm alpine ping company-server
  ping: bad address &apos;company-server&apos;
  </pre>
  <p>Also using the IP from the 'company-server' doesn't work.</p>
  <p>A ping outside the container works, no matter using the name or IP.</p>
  <p>The resolv.conf looks correct to me.</p>
  <pre><b>[maurice@laptop</b><b> ~</b><b>]$</b> docker run --rm alpine cat /etc/resolv.conf
  # Generated by NetworkManager
  search lan
  nameserver 10.1.0.250
  nameserver 10.1.0.253
  nameserver 192.168.86.1
  </pre>
  <p>What I have found out so far.</p>
  <p>If I downgrade packages glibc and lib32-glibc to version 2.32-5, the ping out of the container works again. Because of dependencies I have also to downgrade gcc, gcc-libs and lib32-gcc-libs to version 10.2.0-4.</p>
  <p>I tried the whole thing with a fresh Pop OS 20.10 installation, same problem.
  I also did a test with another VPN (OpenVPN) which worked fine. However, this was only a test scenario and cannot be used as an alternative.</p>
  <p>I have been looking for a solution for several days but have not found anything. It would be really nice if someone could help me with this.</p>
