Connectors are most commonly installed behind your firewall where they can access (connect) to your back end systems in order to read/write data. If you use the Live Forms Cloud hosted server you must ensure that your Connectors are accessible from our servers. This is done by opening up one of the following ports on your firewall:
We recommend that you use https and not http. Https is a secure channel.
