Cisco ONS 15600 Reference Manual, R7.2
Chapter 9 Management Network Connectivity
9.5 External Firewalls
The following ACL (access control list) example shows a firewall configuration when the SOCKS proxy
server gateway setting is not enabled. In the example, the CTC workstation's address is 192.168.10.10.
and the ONS 15600 address is 10.10.10.100. The firewall is attached to the GNE, so the inbound
direction is from CTC to the GNE and the outbound direction is from the GNE to CTC. The CTC
Common Object Request Broker Architecture (CORBA) Standard constant is 683 and the TCC CORBA
Default is TCC Fixed (57790).

The following ACL (access control list) example shows a firewall configuration when the SOCKS proxy
server gateway setting is enabled. As with the first example, the CTC workstation address is
192.168.10.10 and the ONS 15600 address is 10.10.10.100. The firewall is attached to the GNE, so
inbound is CTC to the GNE and outbound is from the GNE to CTC. CTC CORBA Standard constant
(683) and TCC CORBA Default is TCC Fixed (57790).
