Based on interpretation of application protocols, DeleGate can be used as a protocol gateway which translates between client-side protocol and server-side protocol.
As a circuit level proxy, a DeleGate server literally conveys transmission bound to a specified server of a specified application protocol on TCP or UDP, or toward arbitrary servers based on Socks protocol.
