If I do a factory reset, does it erase what we have on the hard disk?
No, any reset of the TC, soft, hard or factory affects the router settings only.. no files are ever deleted without your express wish to delete them.
I have to work with the bridge mode with our satellite internet service.
Ah.. satellite service. Always a problem.
They do not give you a public IP.. the majority of them are cheap skates and give people private IP in the 10.x.x.x range which is problematic on the TC.
Please check the IP in the airport utility.
And you cannot use the TC in bridge.. sorry but this is wrong.. you must use double NAT. for which you will get an error but it is still required to run multiple devices.. otherwise your experience is correct.. only one device can connect at a time.
So in your airport utility click the TC.. and look at what IP address you get.. that is the WAN IP.
It makes life so much easier if you do post a screenshot.. I have shown you mine.. there is nothing here that can allow you any access to my system.. and even having the serial number is useless.. you can blot it out via edit in preview if you are worried.
If that wan address is 10.x.x.x please go to the Edit.. and then the Network Tab, Change the TC to be router, ie NAT and DHCP.. Then to to Network options and change the IP range of the TC to 192.168.1.x
Thusly.. Don't worry about my strange IP range.
Go to network options.
If it is 10.x.x.x click on the DHCP range and change it to 192.168.
The TC will take the first address in the range.. ie from default it will be 192.168.1.1 and the range will be 2-200
Now you can save and then update the TC..
A flashing amber will appear and it will give you a double NAT fault.
Open the summary page again.. click on the fault under status and choose to ignore it.
Again my screenshots are of a different issue but showing you where to find things.
That doesn't fix the fault.. but it will make the TC happy and green..
There is no way to fix the fault because Satellite ISP do not provide you true public IP.
