Question: Port forwarding

When I try to Port forward on my Apple airport it seems to disrupt all other devices using it wirelessly or plugged. Is there a way to use Port forwarding and not disrupt other devices?

We need a lot more information to be able to begin to troubleshoot this issue.


What is the make and model number of your modem?


We ask this because Port Mapping cannot be set up correctly on the AirPort Extreme......unless.....you have a simple modem. Something like the example below which illustrates that a simple modem will have only one Ethernet port.

If the device that you call your "modem" looks something like the example below.....with multiple Ethernet ports.....you cannot set up Port Mapping on the AirPort router correctly. Port settings must be configured on your "modem".

We don't know why you feel that you need to set up port settings. Can you please provide more information about that?


We don't know whether you might be trying to use a PC, a Mac, or an iPhone / iPad to set things up. Can you please provide more information about that?


If you have a Mac, can you confirm on what operating system is it running?


Can you please confirm on which Apple AirPort router that you have? A model number would be really helpful.

Without knowing your current network configuration and what services you are trying to use port forwarding for, it will be a bit difficult to assist you with a solution.


So ... let's start with the following bits of information:

  • What is the make & model of the Internet modem, router, or gateway device that you have your AirPort base station directly connected to by Ethernet (wire)?
  • What is the exact model of your AirPort base station?
  • What service(s) are you trying to set up port forwarding for?

Arris SBG6782 Wireless Modem, Apple airport 7.7.9, and I am trying to Port forward so I can use terminal to ssh into a computer (pi).


As mentioned when going through the airport instructions to Port forward, it affects connection of other devices?

You have a modem/router......not a simple modem. Please review the examples above.


Port Forwarding or Port Mapping will need to be set up on the Arris modem/router.....not on the AirPort.


The AirPort needs to be set up in Bridge Mode. Then, it will simply pass through the port information from the Arris modem/router to your devices.

Bob pretty much summed up what would be required. Your "modem" is actually a combination modem and wireless router. Also known as a gateway device. You would need to configure port forwarding on it, and as Bob mentioned, your AirPort would need to be configured as a bridge.
