If I recall correctly, almost all the system admins are paranoid about security? Is that right? :) I know what a DMZ is and the config you are watching above is for *debuging* purpose only. # Yet don't let my boss know it. > > > > Truy c?p whatismyip.com <http://whatismyip.com> em ???c b?o global IP > > c?a em (n?u c?) l? 58.187.123.232 > But are you sure it's your real public IP address and not that of a > transparent proxy between you and this site?

The router reports that my WAN address is 58.187.122.60. However, as I look at tracert's output, I can tell that that IP is not correct and is different from the IP that whatismyip.com reports. the correct one is 192.168.255.17 or something in its class.
