I'm using CrashPlan backup program to back up server data to

Customer Question

I'm using CrashPlan backup program to back up server data to my computer. But it won't connect due to firewall blocking, so I added crashplan through window filrewall but still not connecting. If I turn off the firewall then it gets connected and start baking up the files but I don't feel safe to turn off server's firewall. How should I fix this issue?

Welcome to, my name is Dustin.
I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.

Expert:  Dustin replied 12 days ago.

Lets find the exact ports Crash Plan is using, and open only those ports for incoming AND outgoing traffic , on each computer or workstation that needs to use crashplan.

This page will help you identify the ports

If you cant find the port, or you are unsure how to allow tcp and udp for incoming and outgoing connections, in windows firewall for a specific port, let me know.

I strive to provide great service, and greatly appreciate a 5 star rating clicked and submitted when you are satisfied.. I always answer follow up questions.

Sorry wrong massage, I'm planing to try your instruction when I go to work
Expert:  Dustin replied 10 days ago.

Understood, Remember the concept here is we only open just the ports that are needed for crash plan..

That way your firewall is still up, but the program is allowed through.. If you run into any issues let me know.
