Hi Martin,
This morning at DockerCon I mentioned to Amir that I had a problem running the mirage-skeleton DNS app on GCE.
He suggested that I contact you to see if you could suggest something.
I'd really like to fix this for a lightning talk I'll do tomorrow.
The problem I have seems to be related to routing.
I receive the DNS request I send to my deployed instance but the response never reaches my client.
I'm running my instance under us-central1 with the default network,
10.128.0.0/20.
So the mirage configure command I use is:
mirage configure -t virtio --ipv4
10.128.0.0/20 --ipv4-gateway=10.128.0.1
My instance has following internal/external ip:
External IP 146.148.68.114 (ephemeral)
Internal IP 10.128.0.3
See below for serial console output (from a few days ago).
Thanks for any suggestion,
Mike.
