Microsoft Forefront Threat Management Gateway (Forefront TMG), formerly known as Microsoft Internet Security and Acceleration Server (ISA Server), is a discontinued network router, firewall, antivirus program, VPN server and web cache from Microsoft Corporation. It ran on Windows Server and works by inspecting all network traffic that passes ...
A typical configuration is a hardened Unix (or Unix-like) machine configured with SSH and a local firewall. An administrator connects to a target machine in the DMZ by making an SSH connection from the administrator's personal computer to the jump server and then using SSH forwarding to access the target machine.
The new connection attempt punches a hole in the client's firewall as the endpoint now becomes open to receive a response from its peer. Depending on network conditions, one or both clients might receive a connection request. Successful exchange of an authentication nonce between both clients indicates the completion of a hole punching ...
The client on the Internet is unaware of the internal network, and cannot tell whether it is communicating with a proxy or directly with a web server. In computer networks , a reverse proxy or surrogate server is a proxy server that appears to any client to be an ordinary web server , but in reality merely acts as an intermediary that forwards ...
Caching of proxy auto-configuration results by domain name in Microsoft's Internet Explorer 5.5 or newer limits the flexibility of the PAC standard. In effect, you can choose the proxy based on the domain name, but not on the path of the URL. Alternatively, you need to disable caching of proxy auto-configuration results by editing the registry.

Port forwarding via NAT router. In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.
A key difference between this approach and running cluster-aware applications is that the latter can deal with server application crashes and support live "rolling" software upgrades while maintaining client access to the service (e.g. database), by having one instance provide service while another is being upgraded or repaired.
While Remote Assistance establishes a Remote Desktop Protocol (RDP) connection to the end user's computer (requires TCP port 3389 to be opened on the client machine and the firewall/NAT/router behind which the machine is), Quick Assist is cloud-based and requires one outbound connection from the helper's PC to the cloud service/Microsoft server ...
