DIY: QuickBooks 2009-2012 firewall ports to open

I'm asked this QuickBooks question approximately five times a week: The Windows firewall won't let QuickBooks into the datafile; what ports do I need to open in order to let the clients in?

The answer is simple, though it depends on the version of QuickBooks being used. I will provide the answers for QuickBooks 2009 to 2012 (and assume you know how to open ports on the firewall for your platform).

QuickBooks 2009

• Pro: ports 80, 8019, 56719, and 55333 through 55337
• Premier: ports 80, 8019, 56719, and 55333 through 55337
• Enterprise: ports 80, 8019, 56719, and 55333 through 55337

QuickBooks 2010

• Pro: ports 80, 8019, 56720, and 55338 through 55342
• Premier: ports 80, 8019, 56720, and 55338 through 55342
• Enterprise: ports 80, 8019, 56720, and 55338 through 55342

QuickBooks 2011

• Pro: ports 80, 8019, 56721, and 55343 through 55347
• Premier: ports 80, 8019, 56720, and 55338 through 55342
• Enterprise: ports 80, 8019, 56721, and 55343 through 55347

QuickBooks 2012

• Pro: ports 80, 8019, 56722, and 55343 through 55352
• Premier: ports 80, 8019, 56722, and 55348 through 55352
• Enterprise: ports 80, 8019, 56722, and 55348 through 55352

You should make sure the directory housing your data file can be accessed through the firewall as well. Opening the ports referenced above should do the trick, but if it doesn't, you might want to temporarily shut off the firewall and see if that allows QuickBooks access. If it does, you might need to add the QuickBooks program directory as an exception for the firewall and then restart the firewall.
