If a port range has been defined for the Layer 4 cluster to which the server is being added, the
Server Port
field
refers to the first port on which to start servicing the cluster’s port range. For example:
If there is no service running on one or more ports in the port range, Equalizer will still attempt to forward
traffic to that port and return an error code to the client, just as if the client was connecting to the server directly.

4. The following screen allows you to associate this server definition with a VMware virtual machine, if Equalizer
VLB is licensed and enabled. See “Associating a Server with a Virtual Machine” on page 299.

Note – For any server in a Layer 4 TCP or UDP cluster, port 20 can only used for FTP traffic in an FTP
cluster (see “Providing FTP Services on a Virtual Cluster” on page 138). Port 20 can be used as part of a
cluster port range starting below port 20 and ending above port 21, but port 20 will not work -- that is, a
service cannot be defined on port 20.
