A PETR is typically used when a LISP site needs to send traffic to non-LISP sites but the LISP site is connected through a service provider that does not accept nonroutable EIDs as packet sources. Proxy ITR (PITR) : A PITR is used for inter-networking between Non-LISP and LISP sites, a PITR acts like an ITR but does so on behalf of non-LISP ...
In the Idle state, BGP initializes all resources, refuses all inbound BGP connection attempts and initiates a TCP connection to the peer. The second state is Connect. In the Connect state, the router waits for the TCP connection to complete and transitions to the OpenSent state if successful.
The protocol is also used by Windows Azure for Point-to-Site Virtual Network. [5] SSTP is intended only for remote client access, it generally does not support site-to-site VPN tunnels. [6] SSTP suffers from the same performance limitations as any other IP-over-TCP tunnel.
Network address translation between a private network and the Internet. Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. [1]
The first firewall (also called the "front-end" or "perimeter" [5] firewall) must be configured to allow traffic destined to the DMZ only. The second firewall (also called "back-end" or "internal" firewall) only allows traffic to the DMZ from the internal network. This setup is considered [4] more secure since two devices would need to be ...
Incoming HTTPS traffic gets decrypted and forwarded to a web service in the private network. A TLS termination proxy (or SSL termination proxy, [1] or SSL offloading [2]) is a proxy server that acts as an intermediary point between client and server applications, and is used to terminate and/or establish TLS (or DTLS) tunnels by decrypting and/or encrypting communications.
The SBC terminates an inbound call and initiates the second call leg to the destination party. In technical terms, when used with the SIP protocol, this defines a back-to-back user agent (B2BUA). The effect of this behavior is that not only the signaling traffic, but also the media traffic (voice, video) is controlled by the SBC.
A well-known host used for initial configuration of a Teredo tunnel. A Teredo server never forwards any traffic for the client (apart from IPv6 pings), and has therefore modest bandwidth requirements (a few hundred bits per second per client at most), [ citation needed ] which means a single server can support many clients.
