Memo Mirantis Fuel 6.1的Internet串連

新版本Mirantis Fuel 6.1，要求Public 網路能連Internet，否則在Verify Networks的時候報錯：

Verification failed.
Repo availability verification using public network failed on following nodes Untitled (b6:4b). Following repos are not available - http://mirror.fuel-infra.org/mos/centos-6/mos6.1/security, http://mirror.fuel-infra.org/mos/centos-6/mos6.1/updates . Check your public network settings and availability of the repositories from public network. Please examine nailgun and astute logs for additional details.

新版本Mirantis Fuel 6.1，要求Public Network能連Internet，否則在後面部署OpenStack的時候報錯如下（我當時沒有等Verify Networks成功就心急去做部署OpenStack了）
