Firewall access rules
If you are behind a firewall that is restricting access to Louper, please ask your network administrator to allow access to the following domains and ports on your network:
There are dynamic subdomains in addition to the above that may be required. We strongly recommend allowing all
louper.io subdomains on your firewall (eg.
For traffic to and from all domains listed above
- TCP 80
- TCP + UDP 443
- TCP 3334
- UDP 3478
- TCP 7881
- UDP 7882
- UDP 10006
- UDP 50000-60000
- TCP + UDP 19302
For RTMP streaming from client to *.louper.io
- TCP 1935
For SRT streaming from client to *.louper.io
- UDP 9999
Please ensure UDP hole-punching is enabled, or disable symmetric NAT. This helps machines behind the firewall establish a direct connection to Louper servers.
Access can be tested using the Connection Tester. For further help or troubleshooting, contact Louper support.
