Can't put AirPort Express into client mode. I followed the instructions for putting an AirPort Express into client mode (https://support.apple.com/en-us/HT201621 for AirPort Utility 6) and my AirPort Express ended up extending the network instead of operating in client mode. What could I be doing wrong?

Make airport express 2 work as router and extend to other routers Hi. sorry for my bad techical knowledge in the description. I've connected my airport express 2 to my main routers LAN1 channel - and this works fine: i have wireless connection from both of them. However when i try to connect a third router to the aiport the internet acces switches between the three routers and i cannot make it work on all three at once. I suspect that it's because i don't have the right configuration on the airport. Does anybody know this issue and have a solution? Kind regards - Victor

When configured for a "default host," that host is fully exposed to the Internet. Port mapping would serve no purpose in this case. On the other hand, port mapping would be used in cases where you only want select ports to be open for that same host.
