Chapter 3 Network Connection ConfigurationAdding Host Aliases30 Application Gateway Administration GuideAdding Host AliasesYou can map Application Gateway host names to IP addresses. The hostaliases that you define override DNS settings.Although the Application Gateway does not include an NIS client andthus does not support commands such as ypbind and nslookup, nameresolution libraries can resolve Application Gateway host names bychecking the /etc/hosts file.To add, review, or remove host aliases, go to the Network > Hosts page ofthe Application Gateway Administration Tool.Note To clear a host alias, select the host and click Clear Host.Configuring RoutesYou can configure the Application Gateway to listen for the routespublished by your routing server(s) or to use static routes that you specify.The Application Gateway supports the Routing Information Protocol(RIP 2).If you use both network interface cards for separate network numbers onthe Application Gateway, you must define a static route so that theApplication Gateway can appropriately handle the traffic destined for thenetwork segment connected to the second Ethernet port.The Default Gateway field on the Network > Interfaces page is relevant toboth dynamic and static routing.• If you enable the Dynamic Gateway option (when configuringdynamic routing), the default gateway will be based on the routingtable, not on the value entered in that field.• If you add a static route, choose the Application Gateway interface notbeing used by the default gateway.The following topics describe how to work with routes:“Configuring Dynamic Routing,” page 31“Adding, Testing, and Removing a Static Route,” page 32“Static Route Example,” page 33
