Network Details

ISP connection

A site that wishes to connect to the CU must provide its own physical (ISP/Internet) network connection.

We are happy to lend technical assistance when requested.

However, we cannot advise anyone to circumvent their institution's AUP.

CU Connection Options

Preferred Option: IPSec
Alternative Option: OpenVPN

IPSec is much preferred to OpenVPN since the former has reduced packet overhead and is routed normally between CU sites.

In particular, OpenVPN requires a fully connected mesh network of point to point links as well as a central VPN server, which would present a single point of failure.

It may be possible that a site cannot (for whatever reason) connect to the CU using IPSec. In such a case, OpenVPN may provide a workaround until IPSec can be implemented.
