Crash Plan

I have Crash Plan installed and have found and issue that I cannot seem to fix. The issue is, when my Firewall is running, Crash Plan Client will not connect to the sever on port 443. When I disable the firewall, Crash Plan can connect. I have made an exception for port # 443, however crash plan client will not connect and will give me the error "Waiting for connection" and will stay like this until I disable the firewall. The program CrashPlanService.exe is even listed under Program Contorl for Custom for all ports etc but still unable to connect. Does anyone have any ideas I can try so I can run Crash Plan and my Firewall together.
