Access security cameras remotely with Windows 2008 RRAS

There is a similar topic discussing this (Access camera/ip remotely through WIndows 10 ZT Client) but I would like to see if someone can provide step instructions on the configurations.

Here is my setup:
Windows 2008 server LAN address (10.10.10.5)
Windows 2008 server ZT address (192.168.100.5)
Camera on LAN address (10.10.10.50)
iPhone ZT address (192.168.100.10)

I would like to be able to use my iPhone to access the Camera IP address on the LAN.

I have read that with Windows 2008 server, there is Routing and Remote Access (RRAS) that helps route the iPhone to access the Camera on LAN address (10.10.10.50). I have enabled RRAS on Windows 2008 server with LAN routing but I’m not able to ping/access the Camera on LAN. I’m not sure what else I need to configure. If anyone can provide step by steps on what other configurations need to be made on Windows 2008 or ZT, I would be much appreciated it.
