NTP-D27 Set Up the ONS 15454 SDH for Firewall Access

Step 6 If you want to complete an address summary, complete the following steps. If not, continue with Step 7. Complete the address summary only if the ONS 15454 SDH is a gateway NE with multiple external ONS 15454 SDH NEs attached with IP addresses in different subnets.

a.In the RIP Address Summary area, click Create.

b.In the Create Address Summary dialog box, complete the following:

•Summary Address—Enter the summary IP address.

•Mask Length—Enter the subnet mask length using the up and down arrows.

•Hops—Enter the number of hops. The smaller the number of hops, the higher the priority.

c.Click OK.

Step 7 Return to your originating procedure (NTP).

NTP-D27 Set Up the ONS 15454 SDH for Firewall Access

Purpose

This procedure provisions ONS 15454 SDH nodes and CTC computers for

 

access through firewalls.

Tools/Equipment

IIOP listener port number provided by your LAN or firewall administrator

Prerequisite Procedures

NTP-D24 Verify Card Installation, page 4-2

Required/As Needed

As needed

Onsite/Remote

Onsite or remote

Security Level

Provisioning or higher

Step 1

Log into a node that is behind the firewall. See the “DLP-D60 Log into CTC” task on page 3-24for

 

instructions. If you are already logged in, continue with Step 2.

Step 2

Complete the “DLP-D67 Provision the IIOP Listener Port on the ONS 15454 SDH” task on page 4-20 .

 

Figure 4-5shows ONS 15454 SDH nodes in a protected network and the CTC computer in an external

 

network. For the computer to access the ONS 15454 SDH nodes, you must provision the IIOP listener

 

port specified by your firewall administrator on the ONS 15454 SDH.
