Windows Firewall question - outbound

Let's say the Windows FW on a server is enabled, and set to deny inbound and oubound traffic on all domains by default. A client try to get to the server for SMB file share. So I create a rule on in inbound from ClientIP to ServerIP on destination port of 445 to be allowed. Now the client is able to access the SMB share on the server. My question is the outbound FW is set to deny by default. When this client sends in a packet let's say from sourceport of 123456 to 445, the returning packet has to go out the server from source port of 445 to the destination port of 123456 on client, since the outbound FW is denying by default, will this returning packet to the client be blocked by the Windows FW? do I need to create a allow rule on the outbound to allow the returning traffic? Thanks.
