Pulse Secure VPN and hostonly adapter

[malcolmm83]

I'm running docker toolbox on a windows 10 laptop using VirtualBox. It works fine when I'm not using the VPN. When Pulse Secure is connected, it overrides the route to 192.168.99.0 255.255.255.0 to point to the VPN. My network services folks tell me that our private network uses ALL the RFC 1918 address blocks, and therefore routes them to the WAN. If the VPN is going to hijack any RFC 1918 addresses, then can I configure Docker to use a different block? Or other suggestions for workarounds? I'm also trying to run minishift, which has got the same problem.

You'll probably want to play with this option and use 10.x.x.x addresses, though if your IT department have used all the RFC 1918 address space you'll probably still have issues.
