13.2.7 IP Scenario 7: Provisioning the ONS 15454 SOCKS Proxy Server
The ONS 15454 SOCKS proxy is an application that allows an ONS 15454 node to serve as an internal
gateway between a private enterprise network and the ONS 15454 network. (SOCKS is a standard proxy
protocol for IP-based applications developed by the Internet Engineering Task Force.) Access is allowed
from the private network to the ONS 15454 network, but access is denied from the ONS 15454 network
to the private network. For example, you can set up a network so that field technicians and network
operations center (NOC) personnel can both access the same ONS 15454s while preventing the field
technicians from accessing the NOC LAN. To do this, one ONS 15454 is provisioned as a gateway
network element (GNE) and the other ONS 15454s are provisioned as end network elements (ENEs).
The GNE ONS 15454 tunnels connections between CTC computers and ENE ONS 15454s, providing
management capability while preventing access for non-ONS 15454 management purposes.
