IP connectivity from a cellular data network to for example your home network is not straight forward
Be aware of the following: + your cellular 3G IP address might be NAT'd (important when you try to reach the mobile device) + your home network IP address is not public reachable (if this is the case try to place your home ip address in a DMZ zone ~possible security risks!!!) Q1: How does your phone know about your home ip address (manually configured)? Q2: Can you ping your home network from outside your LAN? --Roman On Mar 2, 10:31 pm, Burgwindeck <[email protected]> wrote: > Hi Gn, > > I also have been trying to setup a Droid to Droid 3G connection. > I can confirm that all works great in wifi mode.
