4750 port opening for NLB (Virtual IP)

Soundappan (BSA FAN) Shanmugam

I have two application servers and one NLB IP, I want to confirm whether i should open port of 4750 from NLB IP or two application servers towards the target servers.

 

NLB IP-->4750 <-- Target Server

Physical IP address1 Physical IP address 2 -->4750 <-- Target Server

 

It might be silly But I need a confirmation..

 

The below link shows that open ports against NLB. I want confirmation from Experts
