SolarWinds NTA port requirements
Supported Version: SolarWinds NetFlow Traffic Analyzer (NTA) 4.2.3 and earlier.

These ports include feature specific requirements including Orion agents, High Availability, and component monitors and templates.
|80||TCP||World Wide Web Publishing Service||
Port used for web console and any other web servers.
Port for outbound traffic if NetBIOS name resolution is turned on. When NTA is trying to resolve the NetBIOS names of servers in their conversations, you may find a large amount of outbound UDP 137 traffic from the NTA collector to a number of external addresses. You can confirm the traffic by using the Flow Navigator to match the outbound connections to existing conversations.
This is normal behavior when NetBIOS is enabled. An easy way to demonstrate the behavior is to disable NetBIOS in NTA and watch all outbound connections terminate.
