I already allowed port range 50000-50100 (tcp) and 10080 (udp) in my
firewall.

Are you sure you did it correctly?
 server udp port 512-1024 to client udp port 10080
 server tcp port 50000-50100 to client any port.

You should try the 'bsdtcp' auth, it is more firewall friendly, it only use:
 server tcp port 512-1024 to client tcp port 10080
