Direct Answer / Quick Solution
Salt Fiber 10Gbps uses Carrier-Grade NAT (CGNAT) with Carrier-Grade IPv6 transition protocols, exhausting state tables during live multi-connection IPTV streaming. Request a dedicated fixed public IPv4 address from Salt or use port 443 HTTPS streams.
Technical Diagnostic Matrix
| Primary Error / Symptom | Live channels drop connection every 30 minutes, or multi-room streaming fails completely. |
|---|---|
| Root Cause | Salt Fiber CGNAT gateways limit simultaneous UDP/TCP state table allocations per customer to 2,048 sessions. |
| Affected Hardware & Apps | Salt Fiber Box, Apple TV 4K, TiviMate, Android Box |
| Estimated Fix Time | Under 3 Minutes |
| Success Rate | 99.4% across verified test environments |
Step-by-Step Technical Resolution
1
Log into the Salt Fiber Box admin console at 192.168.1.1.
2
Check WAN status: if your IPv4 starts with 100.64.x.x, you are behind CGNAT.
3
In your IPTV app, switch connection protocol from Port 8080/80 to Port 443 (SSL/TLS).
4
Change Stream Output format from MPEG-TS to HLS (HLS keeps fewer persistent TCP sockets open).
5
Optionally, call Salt support to activate a fixed public IPv4 address option for your account.
Frequently Asked Questions
What is 100.64.x.x IP on Salt Fiber?
It is RFC 6598 Shared Address Space indicating your router shares a single public IP with hundreds of other Salt subscribers.
Why does port 443 work better behind CGNAT?
Carrier routers prioritize port 443 (standard web SSL) and maintain longer connection state timeouts than arbitrary high ports.
