Setting up a private Cloud on my University's Openstack Cloud. We are going to install sql server on two windows 2012 server virtual machines. So naturally i want install sql server by downloading it to these machines. I did have internet access, now i do not. The College It say i have something blocked. Do i have to do some configuration to simply get internet access on these servers so i can simply download stuff?

Note: there's also a Heat template to deploy SQL Server if you want to automate it:

Are you able to ping ? If you can ping but not able to open any webpage , the issue must be MTU range.

Default value of MTU is 1500 but in some cases you should adjust it to correct value that suits your environment. In most case MTU 1456 will work.

Deployment Windows 2012 R2 Evaluation on RDO ML2&OVS&VXLAN system works fine with MTU=1500.
Only ML2&OVS&GRE configuration requires MTU=1454.

Cloudbase-init sets the MTU automatically if your DHCP service provides it as an option.

Otherwise, as @vinoth suggests, make sure to set the MTU manually
