The ICMP is accepted because you have "Accept ICMP [Before Last]" in your
policy properties.

The 58103 is because CheckPoint understands the FTP protocol and you do
not. FTP works like this: You connect to the FTP server. Then your client
gives the FTP server a port that it wants to accept the data connection
on. Your client then opens this port and waits for the FTP response.
CheckPoint understands this and allows the traffic (As it is supposed to).
