Network Requirements
Please request your IT manager to ensure access to the NEI system from your corporate servers.
| Hostname | IP address | Ports (outbound) |
|---|---|---|
| ne.institute | Load balancer — no static IP | 443/TCP |
| app.ne.institute | Load balancer — no static IP | 443/TCP |
| livekit.ne.institute | 54.95.166.248 | 443/TCP, 7881/TCP, 7882/UDP, 443/UDP |
| turn.ne.institute | 54.95.166.248 | 443/TCP, 7881/TCP, 7882/UDP, 443/UDP |
| relay.ne.institute | 13.192.72.189 | 443/TCP |
All rules are outbound from the participant’s device; no inbound rules are required. The 443/TCP rules are mandatory for a call to connect; the UDP and 7881/TCP rules carry direct media and materially improve call quality and latency.
These destinations must also be excluded from SSL/TLS inspection. This traffic is WebRTC, WebSocket and TURN-over-TLS, not ordinary HTTP. An inspecting proxy completes the TLS handshake and then drops or throttles the long-lived flow, so the call appears to connect but has no audio or video. Opening the ports without an inspection exemption will not work.
