Gateway

Defining address pool options

You can use a session policy or the global Citrix Gateway settings to control whether or not intranet IP addresses are assigned during a user session. Defining address pool options allows you to assign intranet IP addresses to Citrix Gateway, while disabling the use of intranet IP addresses for a particular group of users.

You can configure address pools by using a session policy in one of the following three ways:

  • Nospillover - When you configure address pools for intranet IP address, you get a session with an available IP from the pool. For users who have used all available intranet IP addresses, the Transfer Login page appears.
  • Spillover - When you configure address pools and the mapped IP is used as an intranet IP address, the mapped IP address is used for users who have used all available intranet IP addresses.
  • Off - Address pools are not configured.

Note: If the mapped IP address is not configured then SNIP is used.

To configure address pools

  1. In the configuration utility, on the Configuration tab, in the navigation pane, expand Citrix Gateway > Policies, and then click Session.
  2. In the details pane, on the Policies tab, click Add.
  3. In Name, type a name for the policy.
  4. Next to Request Profile, click New.
  5. In Name, type a name for the profile.
  6. On the Network Configuration tab, click Advanced.
  7. Next to Intranet IP, click Override Global and then select an option.
  8. If you select SPILLOVER in Step 9, next to Mapped IP, click Override Global, select the host name of the appliance, click OK and then click Create.
  9. In the Create Session Policy dialog box, create an expression, click Create and then click Close.

Configuring the transfer login page

If a user does not have an intranet IP address available and then tries to establish another session with Citrix Gateway, the Transfer Login page appears. The Transfer Login page allows users to replace their existing Citrix Gateway session with a new session.

The Transfer Login page can also be used if the logoff request is lost or if the user does not perform a clean logoff. For example:

  • A user is assigned a static intranet IP address and has an existing Citrix Gateway session. If the user tries to establish a second session from a different device, the Transfer Login page appears and the user can transfer the session to the new device.
  • A user is assigned five intranet IP addresses and has five sessions through Citrix Gateway. If the user tries to establish a sixth session, the Transfer Login page appears and the user can choose to replace an existing session with a new session.

Note: If the user does not have an >assigned IP address available and a new >session cannot be established by using the >Transfer Login page, the user receives an >error message.

The Transfer Login page appears only if you configure address pools and disable spillover.

Configuring a DNS suffix

When a user logs on to Citrix Gateway and is assigned an IP address, a DNS record for the user name and IP address combination is added to the Citrix Gateway DNS cache. You can configure a DNS suffix to append to the user name when the DNS record is added to the cache. This allows users to be referenced by the DNS name, which can be easier to remember than an IP address. When the user logs off from Citrix Gateway, the record is removed from the DNS cache.

To configure a DNS suffix

  1. In the configuration utility, on the Configuration tab, in the navigation pane, expand Citrix Gateway > Policies, and then click Session.
  2. In the details pane, on the Policies tab, select a session policy and then click Open.
  3. Next to Request Profile, click Modify.
  4. On the Network Configuration tab, click Advanced.
  5. Next to Intranet IP DNS Suffix, click Override Global, type the DNS suffix and then click OK three times.
