By default, CF app containers get the DNS configuration of the cell host. This has BOSH DNS as the first DNS server. The IP tables rules on the cell drop traffic from app containers to BOSH DNS, so DNS requests to this server time out.

This may be fixed if we hook up silk to garden.
A workaround is manually overriding the garden dns_servers setting to your DNS server list without the BOSH DNS IP.

Is this still an issue? Was this in the 1.x release branch, or in the 2.x prereleases?
