When using PDAnet on a PC (Win7 ultimate) to USB tether a Motorola Droid on Verizon 3G the IP address of the PC appears to be public - 64.245.171.115 (64-245-171-115.pools.spcsdns.net) - but connections show as coming from another public IP - 97.14.69.212 (212-sub-97.14.69.myvzw.com).

Someone is performing Network Address Translation - either PDAnet or within the Verizon 3G network.

Can someone tell me who is doing the NAT? Is it PDAnet or is it at Verizon?

Is there any possibility of setting up port forwarding, such that connections to the public IP 97.14.69.212 (212-sub-97.14.69.myvzw.com) are forward to the PC?

We are testing a network protocol that requires either a true public IP or forwarding a range of ports from the public Internet to the system on which the software runs (actually Linux hosted by VMware Player or Workstation on a PC running Windows).
