Bug Passive port range - in firmware 1.08

Problem Type: FTP Server passive port range allows to enter more than 5 digits

□ Error message  X Function does not work  □ Enhancement  □ UI Wording  □ Other:___________

Problem Description:

In the settings for the FTP server, you can manually select the range for your passive ports.
I used 30000 - 30020.
But "finger error" I entered in the first field 300000. (one zero to much)
There is no limit to enter only max. 5 digits as port. (1 - 65535)

Function Tested:

Entering passive port 300000.
DNS-323 accepted it, and showed in GUI: "FTP Server Status: Status = Started"
But no FTP port was open when I scanned my DNS-323 with nmap.
First after entering the correct "only 5 digits" passive port range, the FTP server was running.

Test Procedure (steps to reproduce):
Passive Mode -> select "Use the following port range:"
Entering: 300000 to 30020
Pressed "Apply".
