VPN

Connecting to the Internet through Virginia Tech's Virtual Private Network (VPN) is the only officially advertised and supported method of accessing certain resources such as VT Network Software from off-campus. Alternatively, you can use SSH tunnels or proxies to obtain a Virginia Tech IP address.

Important: You must first create a Remote Access ID to be able to log into the VPN. This is different from your normal VT PID password. This is the Network Account information on your Accounts page.
