For starters your xml needs to be edited.
<!-- Only specify these two if you really think you need to. -->
<!--<address>Serving Machines IP</address>-->
<!--<localaddress>127.0.0.1</localaddress>-->
Needs to be changed to
<!-- Only specify these two if you really think you need to. -->
<!--<address>97.82.210.231</address>-->
<!--<localaddress>192.168.1.100</localaddress>-->
Secondly, your router can be tweaked a bit as you are doing redundant tasks by having port forwarding and DMZ setup.
Turn off DMZ
In port forwarding, you need 3 lines:
World:start 9000:End 9000:Both TCP/IP:IP Address 192.168.1.100:Enable checked
Zone:start 7000:End 7500:Both TCP/IP:IP Address 192.168.1.100:Enable Checked
Login:start 5998:End 5999:Both TCP/IP:IP Address 192.168.1.100:Enable checked
