During the week of 8/21/23 we will be implementing a change that will impact Wowza CDN workflows. **Who does this effect?:** If you are using a Wowza Streaming Engine pull to Wowza CDN workflow and you whitelist Wowza CDN IP addresses in your firewall you will need to take action to prevent disruption of your streams. **What do I need to do?:** Prior to 8/21/2023 please add the new IP addresses into your workflow: 129.153.100.158 129.153.114.13 129.154.207.194 132.145.253.238 138.3.255.30 141.147.1.186 146.56.156.1 158.101.43.210 193.123.241.42 After 8/24/2023 please remove the legacy IP’s from your workflow as they will no longer be valid: 34.81.115.95 34.159.18.6 35.198.130.93 35.202.71.195 35.238.167.42 130.211.240.176 Further details can be found in the below article in step 9: > **[Stream to Wowza CDN over HLS](https://www.wowza.com/docs/how-to-stream-to-wowza-cdn)** > > Stream from Wowza Streaming Engine to Wowza CDN destinations in Wowza Video.
