A virtual port in a SoftLayer load balancer is simply the port you wish to run the service on. An example would be port 80 for HTTP.
Our load balancers are proxy based.
This is currently not supported. A new order for a load balancer with SSL offloading will need to be placed.
Load balancers should be installed and available for your configure about five minutes after purchase.
This option is only available by opening a ticket.
The most common ones are ports like HTTP (80), HTTPS (443), FTP (21), DNS (53), POP3 (110), and SMTP (25). Any service can be load balanced, however.
This is possible but only with a persistent balancing method. Other methods are not supported since the traffic is encrypted.
SoftLayer offers multiple balancing methods, including both single and hybrid methods. Refer to the table below for more information about each load balance method we currently offer.

Yes. Both IPv6 and IPv4 are supported on the SoftLayer public network.
Yes, the NetScaler is the only SoftLayer load balancing product that extends into the private network.
Yes, the Use Source IP (USIP) parameter can be set to "YES" within the NetScaler Advanced Management Interface to allow reporting of the client's source IP instead of that of the NetScaler.
Enabling the USIP address mode on the appliance adds flexibility to the appliance to use the client IP address, available in the IP header, when communicating to the server. By enabling this mode, the appliance opens server connections with the client IP address and also factors the client IP address in connection reuse. Therefore, this mode facilitates limited reuse per client based on client IP address.
The NetScaler MPX 11515, 11520, 11530, 11540, 11542. Please contact Sales for pricing information and to order.
Port 3010, for synchronization and command propagation. UDP Port 3003, to exchange heartbeat packets.
NetScaler VPX bandwidth limits are enforced for traffic inbound to the NetScaler only, regardless of whether this is request traffic or response traffic. This indicates that a NetScaler VPX-1000 (for example) can process both 1 Gbps of inbound traffic and 1 Gbps of outbound traffic simultaneously.
Standard and Platinum editions for NetScaler VPX, Enterprise and Platinum Edition for MPX.
Yes, this feature is known as NetScaler Gateway™ and is included in all editions. For more information regarding this feature please visit Citrix website: http://support.citrix.com/proddocs/topic/netscaler-getting-started-map-93/ns-hrdwre-ns-editions-con.html
This is normally caused by the outgoing port of the load balancer being set to port 443. If load balancing is enabled outbound traffic, to your server, will need to be set to the non-SSL port of your server. This is typically port 80 for HTTP.
This is possible in certain configurations. The general rule is one SSL certificate per Virtual IP (VIP). A local load balancer only supports a single VIP but this can be increased on our dedicated and enterprise load balancers.
