You can configure Citrix Gateway virtual servers to restrict the ability for a virtual server to listen on a specific VLAN. You can create a wildcard virtual server with a listen policy that restricts it to processing traffic on the specified VLAN.

The configuration parameters are:

Parameter	Description
Name	The name of the virtual server. The name is required and you cannot change it after you create the virtual server. The name cannot exceed 127 characters and the first character must be a number or letter. You can also use the following characters: at symbol (@), underscore (_), dash (-), period (.), colon (:), pound sign (#), and a space.
IP	The IP address of the virtual server. For a wildcard virtual server bound to the VLAN, the value is always *.
Type	The behavior of the service. Your choices are HTTP, SSL, FTP, TCP, SSL_TCP, UDP, SSL_BRIDGE, NNTP, DNS, ANY, SIP-UDP, DNS-TCP, and RTSP.
Port	The port on which the virtual server listens for user connections. The port number must be between 0 and 65535. For the wildcard virtual server bound to a VLAN, the value is usually *.
Listen Priority	The priority that is assigned to the listen policy. Priority is evaluated in reverse order; the lower the number, the higher the priority assigned to the listen policy.
Listen Policy Rule	The policy rule to use to identify the VLAN to which the virtual server must listen. The rule is: CLIENT.VLAN.ID.EQ (`<ipaddressat>`) For `<ipaddressat>`, substitute the ID number assigned to the VLAN.
