What are the conditions that colleagues from remote location access suiteCrm???
Can you elaborate or expand on your requirement?
Do you mean remote access via the browser or remote server access?
I mean remote server access
You would need to provide us with more details on your requirement.
How do you want users to access and how do you want to restrict access?
If you place SuiteCRM on a server, you could restict access via VPN and then use LDAP/Active Directory for a single sign on solution if this is what you require?
