NAT is working then stops????

Start off by saying pfsense RULES. Have 10 apartment buildings up and running in AP mode. 12 apartments in each building. (120 Apartments)
Current Setup
Gateway dual wan 1 lan pfsense captive portal dhcp squid Manual NAT Sticky Connections Wan 192.168.0.1/24 Wan2 192.168.1.1/24 lan ip 10.0.1.254/24
pfsense 2 - wan 10.0.1.2/24 (pfsense) lan - 10.0.1.3/24 bridged Access Point
pfsnese 3 - wan 10.0.1.4/24 (pfsense) lan - 192.168.2.1/24  infrastructure

I have now created the current layout. (See example Image below) Everything is working fine with the structure as far as internet access to the members. I have Geovision DVR's in each building and have created different access ports on each of the client DVR'S. List of current DVR computers.

Ports needed: 81 4550 5550 Building A DVR IP Lan 192.168.2.0/24
Ports needed: 82 4551 5551 Building B DVR IP Lan 10.0.1.25/8 OFFICE
Ports needed: 83 4552 5552 Building C DVR IP Lan 192.168.3.0/24
Ports needed: 84 4553 5553 Building D DVR IP Lan 192.168.4.0/24
Ports needed: 85 4554 5554 Building E DVR IP Lan 192.168.5.0/24
Ports needed: 86 4555 5555 Building F DVR IP Lan 192.168.6.0/24
Ports needed: 87 4556 5556 Building G DVR IP Lan 192.168.7.0/24
Ports needed: 88 4557 5557 Building H DVR IP Lan 192.168.8.0/24
Ports needed: 89 4558 5558 Building J DVR IP Lan 192.168.9.0/24
Ports needed: 90 4559 5559 Building K DVR IP Lan 192.168.10.0/24

On my client PFSENSE boxes I have a different subnet & ports for the dvr computers in each apartment building. My plan is to be able to access the DVR via Internet address. eg: buildinga.example.com
My question is what would be the best way to make this happen? Have to say the more I deal with PFSENSE the more excited I become. Sorry the example image is so busy.

Setup client DVR this morning and it worked fine. Came back about 3 hours later and it is not working now. Does anyone know why this would be happening? Here are some snapshots of my rules on building E. Thanks, Ken

I have fixed this problem by setting all the networks to a /24, and adding the destination network to the pfsense1 rules. All is working well now. My Wireless setup is located here http://forum.pfsense.org/index.php/topic,10077.0.html
