Topology
- When using the Topology screen, you can set up SSL Orchestrator in an array of topologies that define the type of traffic (transparent or explicit) and the direction of traffic flow (inbound or outbound) you wish to inspect.These deployment settings, which can be modified as needed without un-deploying a configuration, are complimented by SSL settings that assist you in defining inbound and outbound decryption, setting your service types (such as HTTP, ICAP, Layer 2 (L2)/Layer 3 (L3) inline, and receive-only/TAP services), creating your service chains and security policies that can be managed through a visual policy editor.Available topologies are based on your initial network setup. Topologies that are not supported by your network setup or licensing will not show as an enabled option.
- L2 InboundandL2 Outboundtopologies are only available for supported L2 wire enabled networks.
- L3 InboundandL3 Outboundtopologies are available for all supported networks.
- L3 Explicit Proxytopology is only available when Protocol is set to either TCP or Any.
- Existing Applicationtopology is available for SSL Orchestrator addon licensed devices. This option is not available for standalone SSL Orchestrator devices.
SSL Orchestrator provides the installation of default or custom outbound interception rules for greater support in defining your listeners and the flexibility to create your own outbound and inbound interception rules.You can specify the L3 Inbound mode as eitherGatewayorApplication. L2 Inbound mode isGatewayonly. Inbound Gateway mode ensures non-SSL and non-HTTP traffic is forwarded and L7 protocols are identified as an outbound deployment. Inbound Application mode enables address translation.L2/L3 Inbound Gateway and Application mode option:- L2 Inbound: OnlyGatewaymode is available with address translation disabled. In Interception Rule,Portdefaults to 0 andDestination Address/Maskdefaults to 0.0.0.0%0/0.
- L3 Inbound: SelectGatewaymode so address translation is disabled. In Interception Rule,Portdefaults to 0 andDestination Address/Maskdefaults to 0.0.0.0%0/0. Or, selectApplicationmode so address translation is enabled. In Interception Rule, specifyPortandDestination Address/Maskvalues.
Inbound Gateway mode ensures non-SSL and non-HTTP traffic is forwarded and L7 protocols are identified as an outbound deployment.In L2 or L3 InboundGatewaymode, theVerified Acceptcheck box appears on the Interception Rule screen inAdvanced Settings.When upgrading from previous releases, if SSL Orchestrator inbound topology had:- L2 inbound topologies, it will map toGatewaymode.
- Port set to a number that is not 0, it will map toApplicationmode.
- Port set to 0 and no LB pool attached, it will map toGatewaymode.
- Port set to 0, with LB Pool attached, a specific mode will not be mapped. The admin can determine ifGatewayorApplicationmode should be selected for that topology using theModeoption in the UI.
After upgrading an L2 Inbound
deployment, the Gateway mode is automatically set. However, you cannot use the Inbound
Gateway mode feature unless you manually edit the topology by selecting the
Enable Inbound Gateway Feature
check
box or manually associate the corresponding -gw_in_t
and -lib
iRules in SSL Orchestrator (in
the Interception Rule step) or using TMUI/TMSH (virtual server).Enabling the inbound gateway feature ensures that non-SSL and non-HTTP traffic can
be forwarded. In addition, L7 protocol, identified as outbound deployment, and HTTP
traffic, can be forwarded and L7 protocol identified as HTTP while also handling
server-speak-first traffic (e.g. IMAP). Enabling this feature may break current
custom iRules.
After upgrading, you can
update an existing L3 Inbound deployment in either
Gateway
or Application
mode if you did not
select the inbound mode value set by the upgrade. For example, if your inbound topology
has not yet been manually modified, an "i" icon appears in front of the name of your
deployment. Mouse over the icon for more information and make edits by clicking on the
name. In addition, an Enable Inbound
Gateway Feature
check box may appear. By selecting it, the corresponding
iRules, -gw_in_t
and
-lib
, will be attached to
this topology. This is a one-time action.
