Answer 1

You can reach your host from your guest by using the default gateway on your VM.

See this answer for an explanation.

By running netstat -rn you can get the default gateway and then use that ip address in your config file of your application.

Running netstat -rn | grep "^0.0.0.0 " | cut -d " " -f10 should give you the correct ip address. (only tested this on my machine)
