2.5.2 Accessing ONS 15454s Behind Firewalls

If an ONS 15454 or CTC computer resides behind a firewall that uses port filtering, you must receive
an Internet Inter-ORB Protocol (IIOP) port from your network administrator and enable the IIOP port
on the ONS 15454 and/or CTC computer, depending on whether one or both devices reside behind
firewalls.
If the ONS 15454 is in a protected network and the CTC computer is in an external network, as shown
in Figure
The ONS 15454 sends the port number to the CTC computer during the initial contact between the
devices using Hyper-Text Transfer Protocol (HTTP). After the CTC computer obtains the ONS 15454
IIOP port, the computer opens a direct session with the node using the specified IIOP port.

CTC computer
If the CTC computer and the ONS 15454 both reside behind firewalls
the CTC computer and on the ONS 15454. Each firewall can use a different IIOP port. For example, if
the CTC computer firewall uses IIOP port 4000, and the ONS 15454 firewall uses IIOP port 5000, 4000
is the IIOP port set on the CTC computer and 5000 is the IIOP port set on the ONS 15454.
