Link Controller special applications

Hi

 

 

I am going to install a link controller with connection to 2 ISP and a FIREWALL that has behind it DMZ with public address.

 

I wanted to know what application need specific handling like FTP.

 

In the documentation there are no guide lines for something else beside ftp. What about rtp that works like ftp or sftp and many other applications that I might not be aware of.

 

Is there any document that can help with this information.

 

 

Thanks
