I updated connection rules like below in the weblgic because i am doing the SSO Integration with webcenter
In the Connection Filter Rules field, enter the syntax for the connection filter rules.
For example:
<webtier IP>/0 * * allow
0.0.0.0/0 * * deny
I enter ip 1.1.1.1 after that i am unable to start the weblogic
Can you please help me any one above problem.
Thanks,
Chandra 

solution for this.
1. Open config.xml
2. Search for <connection-filter> tag
3. Verify if it has no value.
4. Delete the tags (<connection-filter></connection-filter>)
5. Start the server
