About
Is your organization using a Firewall or VPN? To configure your firewall to work effectively with Kaltura's Real-Time Communication (RTC) solutions, you need to allow specific network traffic to pass through the firewall.
Checklist
To participate in Kaltura Webinars, Kaltura Meetings and Kaltura Virtual Classroom, please ensure that the network you are connecting from allows for the following:
| Protocol | Ports | URL | Addresses |
| TCP TCP/TLS UDP | 443 443 80,443 | *-turn.newrow.com | 3.70.195.32/27 44.199.182.96/27 3.99.123.208/28 15.228.143.96/28 35.86.65.48/28 13.214.124.16/28 3.110.59.16/28 3.38.131.128/28 3.26.132.224/28 35.76.250.144/28 16.163.33.96/28 |
| TCP TCP/TLS UDP | 443 443 80,443 | *-turn.kme.kaltura.com.cn | 71.131.196.48/28 |
TURN protocol messages should not be blocked to the above addresses.
To ensure uninterrupted real-time connections, you must allow all traffic to the following domains through any VPN, firewall, or security software:
- *.newrow.com
- *.kaltura.com
- *.kaltura.com.cn
- *.kme.kaltura.com.cn
You can use this test page to test your traffic rules and see if any IPs or ports are blocking traffic from your end.
Troubleshooting connectivity issues
If presenters or participants experience disconnects, trouble joining the stage, screen sharing issues, or other connectivity problems, they should bypass any VPN and disable network security firewall/proxy services (e.g., Zscaler, Netskope). If this resolves the issue, the IT team will need to add specific exceptions in these products for Kaltura Meetings and Virtual Classroom to work while keeping these services enabled.
