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 frevvo 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.
- HTTP Ports: 80, 8082 or 19080
- HTTPs Ports: 443, 8443 or 19443
For customers that use firewall white-listing, also make sure the frevvo cloud outgoing server IP 220.127.116.11 (host outgoing.frevvo.com) is added to the list.
