Date Thu, 13 Nov 2014 18:54:34 GMT


ASF subversion and git services commented on CLOUDSTACK-6432:

Commit 76f5f3048e115c5ba25ec09a44e4947b5b290ebb in cloudstack's branch refs/heads/4.3 from
[;h=76f5f30 ]

CLOUDSTACK-6432: Blocking DHCP server to service DNS outside network

This would cover only DHCP only network since in basic and shared network, the
private IP used by VR and network may expose to outside.

(cherry picked from commit a554ebdf750be2ff2fd02fda38713b40313fcca8)

> In basic and shared network, VR use private network nic for dhcp/dns services. But if
private network is on the internet as well, it would make VR facing outside network.
> We would restrain the VR DNS service inside CloudStack managed network.
