TURN Server
Run your own TURN (RFC 8656) server in Delphi. Allocate relayed transport addresses for clients that cannot establish a peer-to-peer path, with long-term credentials and per-allocation quotas.
Run your own TURN (RFC 8656) server in Delphi. Allocate relayed transport addresses for clients that cannot establish a peer-to-peer path, with long-term credentials and per-allocation quotas.
A self-hosted TURN server — processes Allocate / CreatePermission / ChannelBind / Send / Refresh / Data, manages allocations and bandwidth, validates long-term credentials.

Enterprise
Set Port + Realm, supply per-user passwords via OnTURNAuthenticate, Active := True — your server now allocates relays for any RFC 8656 client.

TURNServer->Active = true;A self-hosted relay — lets your WebRTC and ICE deployments stop depending on third-party TURN providers.
Honours Allocate requests with REQUESTED-TRANSPORT, picks a free relay port and tracks lifetime. Refresh extends the allocation; the server tears it down on expiry.
Tracks per-allocation peer permissions and channel bindings. Drops Send/Data frames for peers that have not been permissioned per RFC 8656 §9.
Both 36-byte Send / Data envelopes and 4-byte ChannelData frames are supported. The relay forwards datagrams between the relayed-transport-address and the bound peer.
OnTURNAuthenticate exposes the username; you return the password — the server validates MESSAGE-INTEGRITY and rotates nonces automatically.
Set Quota.MaxAllocationsPerUser, Quota.MaxBandwidthKbps, Quota.AllocationLifetime to bound abuse. OnQuotaExceeded reports rejections.
Toggle the underlying server's transport — UDP, TCP and TLS over TCP are all supported. WebRTC clients pick whichever traverses their NAT.
