I believe the problem is now resolved

The only things I changed was that my hosts file was wrong, the IP for the servers FQDN was incorrect but I'm not sure this is what it was
I also turned off ip forwarding with sysctl -w net.inet.ip.forwarding=0
Even though natd, and the firewall have been disabled. must be a weird OSX thing

Sorry for wasting your time guys and thanks for the help
