Autodiscovery failure
Without simplified routing, if a SteelHead is installed in a different subnet from the client or server, you
must define one router as the default gateway and static routes for the other routers so that traffic is not
redirected back through the SteelHead. In some cases, even with the static routes defined, the Access
Control List (ACL) on the default gateway can still drop traffic that should have gone through the other
router. Enabling simplified routing eliminates this issue.
Simplified routing has these constraints:
• You can’t enable WCCP.
• The default route must exist on each SteelHead in your network.
For detailed information, see the SteelHead Deployment Guide .
To enable simplified routing
1. Choose Networking > Networking: Simplified Routing to display the Simplified Routing page.
2. Under Mapping Data Collection Setting, complete the configuration as described in this table.
3. Click Apply to save your settings to the running configuration.
4. Click Save to save your settings permanently.
Autodiscovery failure
When autodiscovery fails, all traffic passes through with the SteelHead in-path (physically or logically).
Possible causes
• Cisco PIX 7.x or Raptor firewalls
• Satellite
• Intrusion Detection System (IDS) or Intrusion Prevention System (IPS)
Control Description
Collect Mappings From Select one of these options from the drop-down list:
• None - Don’t collect mappings.
• Destination Only - Collect destination MAC data. Use this option in connection-
forwarding deployments. This is the default setting.
• Destination and Source - Collect mappings from destination and source MAC
data. Use this option in connection-forwarding deployments.
• All - Collect mappings for destination, source, and inner MAC data. Also collect
data for connections that are un-NATted (connections that aren’t translated using
NAT). You can’t enable this option in connection-forwarding deployments. We
recommend that you use this option to maximize the effects of simplified
routing.
