1. D = deny, NA = not applicable, OK = do not deny
2. CORBA IIOP = Common Object Request Broker Architecture Internet Inter-ORB Protocol
3. BLSR = bidirectional line switched ring
The following ACL 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 15454 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. The CTC CORBA Standard constant is 683 and the TCC CORBA
Default is TCC Fixed (57790).

The following ACL 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 15454 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 is 683 and the TCC CORBA
Default is TCC Fixed (57790).
