Suitebox attempts to dynamically negotiate firewall friendly ports, and private network firewall configurations are unlikely to cause issues.
However, with a high security firewall, such as those found in corporate environments, you may have to ask that your IT team open certain ports.
To check if you are currently blocked from using SuiteBox, you can run this simple test.
A successful test should show the following results:
If you see 4 green ticks then you are good to go.If you find the test fails or you don’t receive 4 green ticks then please ensure the following minimum requirements:
- TCP port 443 is open to outbound SSL and non-SSL
- Whitelist *.tokbox.com and *.opentok.com domains
- Whitelist the following HTTPS verification servers for our HTTPS certificate:
- Along with the minimum requirements, opening UDP Port 3478 will give you a better experience. UDP is highly recommended over TCP for better quality audio and video
This port only accepts inbound traffic after an outbound request is sent. The connection is bidirectional but is always initiated from the corporate network/client so it is not possible for an external entity to send malicious traffic in the opposite direction. For the best possible experience, we recommend opening UDP ports 1025 - 65535
Application firewall requirements
Application servers using the TokBox server SDKs or REST API only need access to outbound web traffic over TCP port 443 with *.opentok.com whitelisted.
