All REDs shut down when camera NATs are turned on

Not sure if this is a NAT question or RED question but here it goes:

We are running 6 RED 15 boxes through an SG 230. I added 3 NAT rules to allow remote video access to our security camera system.

After turning on these rules, then trying to access the cameras (NVMS7000 app), we can see the cameras but it shuts down all REDs. Turning off NAT rules allows the REDs to work once again.

I am DNATting ports 84 & 8014, 85 & 8015, 87 & 8017 to three separate DVR systems.

None of the logs indicate a bandwidth, firewall or other issue and the ports shouldn't interfere with the REDs. Anything?

Thanks, Tom

Edit: These are typical in the RED live log when the REDs go down
