Unable to connect to Client - Firewall and NAT

Dear Michael,
I am not able to get my server to connect to my client. The server are now running the new version that supports ReverseClients. This is what my config file looks like on my first server:
>>Config file start>>>
ReverseClients=185.21.146.211:7575
It=1506438566
DeviceIdMap=USB\VID_05E3&PID_0610\7&1E2C705A&0&1,USB\VID_0B95&PID_1790\0000051BD014A6,4,1,USB\VID_05E3&PID_0610\7&1E2C705A&0&1,USB\VID_0403&PID_6001\A104SF4Z,1,2,USB\VID_413C&PID_2513\6&1BC6F0F8&0&4,USB\VID_045E&PID_0039\7&3270E9A9&0&1,1,3,USB\VID_413C&PID_2513\6&1BC6F0F8&0&7,USB\VID_03F0&PID_E207\7&1E2C705A&0&2,2,4,USB\VID_413C&PID_2513\6&1BC6F0F8&0&7,USB\VID_03F0&PID_0024\7&1E2C705A&0&3,3,5,USB\VID_8087&PID_0024\5&EDDA844&0&1,USB\VID_0C45&PID_648B\6&22170300&0&5,5,6,USB\VID_8087&PID_0024\5&EDDA844&0&1,USB\VID_413C&PID_8197\20689D6543DF,4,7
>>>Config file end>>>

Am I missing anything in my config-file or do I need to configure anything on the client side in order to get the connection?

Thank you for excellent support!

Please ignore this post. It works now :-)

It as unclear to me what ports that was being used TO the Client and TO the Server. Now I know that it must be TCP 7573 that is suppose to be open for the communication from the server to the client and TCP 7575 from the client to the server.

An order will come in a moment!
