I am currently working on a project where we are integrating Salesforce with SAP. Currently, we are trying to open our firewalls to allow traffic to/from cs18.salesforce.com, our Sandbox. However, we do get some errors when opening the IP's in our firewall. 

This is what we have opened:
96.43.146.188
96.43.146.189
96.43.146.60
96.43.146.61
96.43.150.188
96.43.150.189
96.43.150.60
96.43.150.61

Ports – 443, 1024–66535 (inclusive) 

This is the error we get:
Unable to create socket
com.sap.aii.af.ra.ms.api.RecoverableException: unable to create a socket: java.io.IOException: unable to create a socket'. Cause Exception: 'unable to create a socket' 

Any advice on where the issue may be? 

Hi,
Is there anyway to control the feed items (or fields) that appear in the Chatter feed on the HOME page? Specific example - If an event is created for a contact that a user is following, the record appears in the feed as a new event created with the subject, location, start date and end date fields. But the contact name does not appear. Is there anyway of forcing the contact name to appear also?

Thank you
