Windows Firewall Exceptions for ACT!

Firewall Exceptions for ACT!


for Performance reasons we strongly recomend to disable the Windows Firewall if you are accessing your ACT from inside.  

Acessing your SQL Server from the WAN, is not recomended due to the delay, if you want to access your ACT Database from outside, you should consider one of the following solutions


  • ACT for web
  • HandheldContact
  • ACT Sync
  • TerminalServer
  • VmWare View
  • Panologic TSE


If you want to access the ACT SQL Server from outside of your Network ( probably a DMZ) you need to open some ports 

By default this are the ports that you will need to configure when having a firewall between your Server and the Client (or Act for Web Server)
