Not able to access internet inside docker windows container
I am working on a corporate network and I tried setting proxy using RUN netsh winhttp set proxy proxy-server=»http://proxy.com:80″ bypass-list=»*.xyz.com» and also imported the registry HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings ipconfig /all inside my container gives below result

Can someone help me in identifying the root cause and fixing this issue.
No internet connection inside Docker containers

I am on Ubuntu 16.04 and not using firewall or corporate proxy server and have tried to restart Docker. Upd: Update in interactive mode fails in the same fashion.
docker exec -ti angry_goodall /bin/bash apt-get update #fails ping google.com #fails with "unknown host" message ping 8.8.8.8 # shows PING 8.8.8.8 (8.8.8.8): 56 data bytes # and than hangs indefinetly sudo apt-get update runs successfully on host, i.e. on my computer outside docker.

Docker container can only access internet with —net=host
Nothing has worked so far save for adding —net=host to the run command, but I can’t build images from a Dockerfile because I can’t use —net=host with the build command.
I ran docker network inspect bridge to checkout the settings for the docker network bridge and noticed that it uses (almost) the same subnet and gateway as my work VPN. Could that be causing an issue? That could also explain why when I connect to my work VPN some of the sites do not load.
This is the result from docker network inspect bridge :
