KUDO Firewall rules

Unless you are using a dedicated server (PaaS), where each server has its own IP address, the following domain names will need to be whitelisted:   

NOTE:

Unless you are specifically informed that you are using KUDO on Paas, then you are using the SaaS variant.

DOMAINS

• *.kudoway.com
• *.kudoway.eu 
• *.tokbox.com
• *.opentok.com

PORTS

• Open the UDP ports 1025 – 65535 ( for the best experience), this has a great impact on the quality of the session;
• Open the TCP port 443
• Open UDP Port 3478  (If you are using KUDO on a dedicated server [PaaS], then this can be blocked and enforced TCP instead of UDP).
• Make sure to open the UDP port 3478 for inbound and outbound traffic for:
  • *.opentok.com 
  • *.tokbox.com
    

HTTPS CERTIFICATE VERIFICATION

• oscp.godaddy.com
• crl.godaddy.com

Using KUDO with a proxy

If the only way to access the Internet from your network is through a proxy then it must be a transparent proxy or it must be configured in the browser for HTTPS connections.

WebRTC does not work with proxies requiring authentication.
