I have set up rules to allow traffic in from the known IPs, in the datacenter as well as on the server but when I enable the firewall it locks me out... I have even done it as Macro and as Protocol
Have you tried enabling logging on the rules?
If you did, I think you could try creating a new rule (maybe a ACCEPT *), trying to log the traffic reaching the 3rd rule, and start troubleshooting from there
