Any data sent to the proxy server is now forwarded, unmodified, to the remote host [3] and the client can communicate using any protocol accepted by the remote host. In the example below, the client is starting SSH communications, as hinted at by the port number in the initial CONNECT request. SSH-2.0-OpenSSH_4.3\r\n ...
A Virtual Hub has full layer-2 Ethernet packet-switching functions like a physical Ethernet switch. Additionally, a Virtual Hub can be configured to define IP packet filter entries to filter the packets through the Virtual Hub. A Virtual Layer-3 Switch has layer-3 IP static routing functions like a physical router. A VPN Server can have local ...
When damaging content is found, local PSB officials can be dispatched to investigate or make arrests.
