Connection to NAO Robot from Different Network -

i working on project nao robot. part of project requires remotely connecting nao robot outside of shared network.

for example: @ friend's house , want control robot located in home. however, not know how external ip nao , therefore cannot connect robot unless in own home.

is possible assign/retrieve external ip remote use?

it possible. have different possibilities:

a) create vpn (virtual private network) between friend's house , house. solution, find robot in friend's network.

b) configure router forward 1 public port of public ip nao's ip. can send commands house's ip. commands forwarded robot.

indeed same problem if want public ip of laptop or tablet.
