gipoy: That's what they told me when we were in the first steps of troubleshooting. You need to follow through with the troubleshooting process. Once they conclude that the problem is due to multiple IP addresses contacting PunkBuster, then they would automatically give you a real IP. This is because they solve it this way:
1) Troubleshoot PunkBuster software issues
2) Troubleshoot local network issues (remove any routers blahblah)
3) Troubleshoot IP address issues
4) Troubleshoot routing issues
I reached 4. After a few days of waiting, it seems PB was fixed, and I was able to play.
Do I have a real IP? Certainly. I go to
www.whatismyip.com and see the IP addressed assigned to my modem in there. It's in a pool 46.19.194.x.
The real IP address you get after troubleshooting (and for free) differents from the one for SOHOs. The real IP you would get is not reachable from the internet. That means that when you establish a connection with a certain server / IP address, the contacting IP address would appear as your own. But no connection can be established from the internet to your IP address. Meaning, if you were to host, let's say, a private match on Modern Warfare 2, and request that your friend connect to your IP address, it wouldn't work. This is because the IP address is not reachable.
