Return Packets from the Server Aren't Routing
Correctly
IP spoofing is enabled
This problem normally occurs in a single network setup. When you enable IP spoofing, clustered servers see the
client's IP address. If the server tries to reply directly to the client, the client will reject the reply (it had sent its
request to a different address).
Run a
to ensure that routes from a server to a client go through Equalizer and not directly back to the
traceroute
client. If Equalizer does not appear, modify the route to include Equalizer. Alternatively, you can disable IP
spoofing.
Web Server Cannot Tell Whether Incoming Requests
Originate Externally or Internally
IP Spoofing is not enabled
Check the cluster's configuration and enable IP spoofing. This causes Equalizer to pass the client's IP address. Make
sure that responses from the server go through the Equalizer.
Why aren't my clusters working if the server status is
"up"?
There are several reasons this could be happening. Make sure that Equalizer is being used as the default gateway on
all your servers, and that the server service or daemon is running. Sometimes additional host or network routes will
need to be added to the clustered servers in single network. The traceroute (Unix) and tracert (Windows)
commands area useful diagnostic tools. Trace from the clustered server back to any client that is not able to resolve
the cluster address. If Equalizer is not showing up as the first hop, routing is the cause of the problem.

Restoring IP Access to the Administrative Interface
The browser-based Administrative Interface can be accessed via the internal IP, the external IP, or the failover IP,
using the
or
protocols. Settings for interface access appear in the configuration file. While the
http://
https://
Administration Interface prevents you from disabling all access to the interface, all access can be disabled if the
access settings are removed from the configuration file manually or if the configuration file becomes corrupted.
If access to the Administrative Interface is disabled on all available IP addresses and protocols, do the following to
enable access again:
