Network Guides¶
About these guides¶
The Network Guides explain how to configure different firewalls to ensure that Reemo can use an optimal connection (Direct/UDP) and avoid unnecessary fallback through relays (Relay/UDP). They are mainly intended for network administrators and IT managers who want to make sure their infrastructure allows Reemo users to benefit from the best possible performance.
Relay/UDP vs Direct/UDP¶
Reemo uses WebRTC Peer-to-Peer networking technology, the same used by many VOIP services. Two connection types are possible:
- Relay/UDP
- Connection using the Reemo infrastructure (relay server located in Paris).Pros: works on all types of networks, even with strict filtering.Cons: adds latency and may cause packet loss.
Note
Since our relay servers are located in France, latency may be high for users in distant regions. Organizations can, however, use their own TURN servers.
- Direct/UDP
- Optimal connection (P2P) between the browser and the remote computer.Pros: best performance, minimal latency.Cons: may require firewall configuration.
NAT Compatibility¶
Here is a compatibility table showing in which cases a Direct/UDP connection is possible:

Note
If your connection is always in Relay/UDP and you want to benefit from the best performance, please refer to the connectivity test page and configure your firewall according to our guides.
