This section includes suggestions for maintaining and troubleshooting your communication with
National Australia Bank
 servers.

Communicating with
National Australia Bank

National Australia Bank
 customers are responsible for the maintenance of their communication with
National Australia Bank
 servers.
Using the various networking tools which are available, customers can resolve the current host names of
National Australia Bank
 servers locally.
National Australia Bank
 applications should be set to direct requests of
National Australia Bank
 hosts to a host name, as opposed to an IP address.
Appreciating that some network applications (firewall software applications, for example) do not allow the use of host names, customers may perform a DNS lookup to resolve a
National Australia Bank
 host name to an IP address; however, customers should be aware that it is their responsibility to maintain the timeliness of the IP resolution for a
National Australia Bank
 host name.

Troubleshooting Communication Problems

While
National Australia Bank
 works to maintain a dependable network environment to which the customer can send requests, the possibility exists for network disruption between
National Australia Bank
 and the customer. In order to ensure that any service disruption has limited impact on the consumer, please be sure to keep the following in mind:
  1. Put an order queue system in place: Customers should have a system that allows them to continue to receive orders from consumers. Such systems might include a database that collects all consumer information and then submits all the collected information once the connection to
    National Australia Bank
     has been re-established.
  2. Collect the following information when working with

    • What server(s) are you trying to access (ics2.ic3.com,
      nab.au.com
