Overview 
If you notice that Monitoring Sessions to the Internet are showing very high packet loss (close to 80% or higher), the problem usually comes from the corporate firewall. In most cases, the traffic sent by the Obkio Agents is being blocked or limited before it can reach the Internet.
Common Causes
- The firewall is blocking the UDP traffic used by the Agents.
- Outbound traffic towards the Internet is not allowed on the required ports.
- A proxy or other security device is filtering the traffic and dropping packets.
Recommended Configuration
To fix this and prevent false results:
- Allow outbound UDP traffic from the Obkio Agents.
- Make sure UDP 23999 port is open.
- Check that the corporate firewall allows direct access to Obkio Public Monitoring Agents.
- If your company uses a centralized firewall, apply the rule globally so that all sites are covered.
