landrush Possible issue with IPv6 resolution

I was working on some Vagrantfiles using ubuntu 12.04 & landgrab without any trouble. Upon switching to ubuntu 13, I've noticed that any connection to hosts that lack a AAAA record (e.g., launchpad.net) fail. Removing landrush gets them working again (albeit slowly).

I could also get them working intermittently by adding a public_network interface. I suspect requests that get routed via the private network are hitting landgrab and failing but the public network requests are succeeding.

Still need to dig in more, but thought I'd file the issue incase there were any known issues with IPv6 passthrough.

We're seeing this problem too.

I've had the same issue... on an Ubuntu 14.04 guest machine I found that I could not clone github.com repositories:

Could not resolve hostname github.com: No address associated with hostname

This appears to explain the issue, relating it to IPv6: http://serverfault.com/questions/578952/ssh-client-name-resolution-fails-for-names-that-are-resolvable
