To view or modify your current adapter settings:

1. In the Administration Console, click Access Manager > Access Gateways > Edit > Adapter List.

   

2. (Conditional) If the Access Gateway is a member of a cluster, select the server you want to configure from the list of servers in the Cluster Member field. All changes made to this page apply to the selected server.

3. Select the adapter you want to modify, then select one of the following actions:

   • To add a new subnet to an existing adapter, click New.

   • To delete a subnet, select a subnet, then click Delete. More than one must be configured for you to delete a subnet.

   • To modify an existing subnet, click the IP address of the subnet.

4. To configure a new subnet or a new IP address for a subnet, configure the following fields:

   

   Subnet: Displays the address of the subnet that you are modifying. This is empty if you are creating a new one.

   Subnet Mask: (Required) Specifies the subnet mask address for this subnet. The address can be specified in standard dotted format or in CIDR format

   IP Addresses: Allows you to manage the IP addresses assigned to the subnet.

   • To add an address, click New, specify the address, then click OK.

   • To delete an address, select the address, then click Delete.

   • To change the IP address, see Section 4.3, Changing the IP Address of the Access Gateway.

5. Click OK.

6. Configure the Adapter List Options.

   These options let you change settings for the network adapters on the Access Gateway to ensure compatibility with an existing LAN. Modify the default settings only if your LAN requires specialized adapter card changes.

   • Speed: Select Default, 10 MB, 100 MB, or 1000 MB.

   • Duplex: Select Default, Half, or Full.

     IMPORTANT:Some network adapter drivers do not correctly detect duplex settings. This is a general industry problem with Fast Ethernet technology.

     If your Access Gateway isn't performing as expected, check to ensure that the duplex settings for its network adapters match your network configuration. It might be necessary to manually configure the duplex settings on both your Access Gateway and your Ethernet switch or hub.

   • NAT: Select Dynamic or Disabled.

     If the Access Gateway is serving as a router, and your network employs non-unique private IP addresses, you can configure the Access Gateway to provide Network Address Translation (NAT) services.

     For example, if you have a 10.0.0.0 private network on eth0 and a registered public network such as 130.0.0.0 on eth1, the clients on the private network can access the Internet through the Access Gateway, provided that the Dynamic option is selected in the NAT drop-down list for the eth1 adapter.

     The Access Gateway then functions as a network address translator and dynamically maps the private, non-routable 10-net addresses to the registered public address assigned to eth1.

     IMPORTANT:You cannot configure a reverse proxy on an IP address assigned to an adapter that has the Dynamic option set for NAT. NAT and a reverse proxy cannot coexist on the same adapter.

   Custom load parameters: (NetWare only) Allows you to specify non-standard load parameters for a custom driver. If you used the custom driver option during installation and the documentation for this driver specified some custom load parameters, enter these parameters in the text box.

8. On the Server Configuration page, click OK, then click Update > OK.

To modify your current gateway configuration:

1. In the Administration Console, click Access Manager > Access Gateways > Edit > Gateways.

   

2. (Conditional) If the Access Gateway is a member of a cluster, select the server you want to configure from the list of servers in the Cluster Member field. All changes made to this page apply to the selected server.

3. Fill in the following fields:

   Enable RIP: (NetWare only) Allows you to turn on the Routing Information Protocol 1. Through this protocol, the Access Gateway is able to learn routes.

   Act as Router: Select this option if the Access Gateway functions as the default gateway for clients on the network. If you select this option, you can specify additional gateways.

   Enable Gateway Statistics Monitoring: Select this option if you want to gather statistics and monitor the traffic on the gateways.

4. Configure your default gateway, which specifies the gateway to use when no other routes apply. Configure the following:

   Next Hop: The IP address of the gateway.

   Metric: A relative number indicating the bias you can add to the normal flow of gateway logic. Specifying a number higher than 1 makes this resource more expensive and alters the gateway logic used. Valid numbers include 1 through 16.

   Type: Gateways are active if they publish their presence, or passive if they do not.

5. Configure your host gateways, which are the gateways to be used for packets being sent to specific hosts. When you select New from the Host Gateway list, you are asked for the following information:

   Next Hop: The address of the host gateway that is to be used.

   Host: The IP address of the destination host. Valid addresses cannot be the first or last address of a class and must be unique.

   Metric: A relative number indicating the bias you can add to the normal flow of gateway logic. Specifying a number higher than 1 makes this resource more expensive and alters the gateway logic used. Valid numbers include 1 through 16.

   Type: Gateways are active if they publish their presence, or passive if they do not.

   Click OK when the fields are configured.

6. Configure your network gateways, which are the gateways to be used for packets being sent to specific subnets. When you select New from the Network Gateway list, you are asked for the following information:

   Next Hop: The address of the gateway that is to be used.

   Network Address: The subnet address for the destination IP address range. You can also enter a specific IP address on a given subnet, and the Access Gateway calculates the subnet address using the mask.

   Mask: The subnet mask for the subnet or IP address above. A valid entry must be at least as large as a class mask where a Class A mask is 255.0.0.0, a Class B mask is 255.255.0.0, and Class C, D, and E masks are 255.255.255.0.

   Metric: A relative number indicating the bias you can add to the normal flow of gateway logic. Specifying a number higher than 1 makes this resource more expensive and alters the gateway logic used. Valid numbers include 1 through 16.

   Type: Gateways are active if they publish their presence, or passive if they do not.

   Click OK when the fields are configured.

8. On the Server Configuration page, click OK, then click Update > OK.

1. In the Administration Console, click Access Manager > Access Gateways > Edit > DNS.

   

2. (Conditional) If the Access Gateway is a member of a cluster, select the server you want to configure from the list of servers in the Cluster Member field. All changes made to this page apply to the selected server.

3. Fill in the following fields:

   Server Hostname: Displays the unique host or computer name that you have assigned to the Access Gateway machine. If you modify this name, you need to modify the entry for the Access Gateway in your DNS server to resolve this new name.

   Domain: Specifies the domain name for your network. Your DNS server must be configured to resolve the combination of the server hostname and the domain name to the Access Gateway machine. This field assumes you are using dotted names for your machines, such as sales.mytest.com, where sales is the Server Hostname and mytest.com is the Domain.

   DNS Server IP Addresses: Displays the IP addresses of the servers on your network that resolve DNS names to IP addresses. You can have up to three servers in the list. If you specified any addresses during installation, they appear in this list. To manage the servers in this list, select one of the following options:

   • New: To add a server to the list, click this option and specify the IP address of a DNS server.

   • Delete: To delete a server from the list, select the address of a server, then click this option.

   • Order: To modify the order in which the DNS servers are listed, select the server, then click either the up-arrow or the down-arrow buttons. The first server in the list is the first server contacted when a DNS name needs to be resolved.

4. Configure the DNS Cache Settings. These options allow you to control the refresh of DNS information. These are all standard DNS options.

   Negative Lookup: Specifies how long a failed DNS lookup domain name remains in cache. If the Access Gateway cannot resolve a domain name, it stores that information in its cache for the specified amount of time. If the Access Gateway receives requests for that domain name within this period, it sends a “Bad Gateway” error message to the browser and does not resolve the domain name again. Valid field values include 0–3600 seconds. The default is120 seconds.

   Minimum Time To Live per Entry: Specifies the minimum amount of time that DNS entries remain in cache before they expire. This is the minimum value the Access Gateway uses regardless of the value the DNS server returns. Valid field values include 0–3600 seconds. The default is 120 seconds.

   Maximum Time To Live per Entry: Specifies the maximum amount of time that DNS entries remain in cache before they expire. This is the maximum value the Access Gateway uses regardless of the value the DNS server returns. Valid field values include 0–744 hours. The default is 168 hours.

   Maximum Entries: Specifies the maximum number of DNS cache entries. When this number is reached, the Access Gateway deletes old entries to make room for newer ones. Valid field values include 2000–100000. The default is 5000.

   DNS Transport Protocol: Specifies the transport protocol that DNS uses on the network where the Access Gateway is installed. Valid values are UDP and TCP. The default is UDP.

   Monitor DNS Server: (NetWare only) If selected, allows the Access Gateway to monitor DNS server availability by pinging the configured servers every minute. This ensures timely handling of DNS requests. You should deselect this item if the Access Gateway accesses DNS through a connection that is not kept continually open, such as a dial-up phone line or ISDN connection.

   Keep in mind, however, that deselecting this option causes the DNS configuration on the Health tab to display the following message: "(Passed) Domain and DNS Servers configured". When this option is enable, the Health tab displays the following message: "(Passed) Domain and DNS Servers configured and active".
