time capsule questions

Hi all

I've just brought myself a TC and wondering about a few things.

I've got an iphone,MBP, dell laptop and PS3.

Now all these use the wireless and only the MBP has N. I've enabled it as mixed mode b/g/n on 2.4ghz.

I understand 2.4ghz has greater distance than 5ghz but this isn't a problem because i'm in the same room with all devices.

But what about the speed. Will I get the full N speed when using just the MBP and only downgrade my speed when another G device attaches? Will this then increase when that G client disconnects again?

All does the HDD inside the TC spin down when not in use and only acts like a wireless AP to save power?


I also see that you can port mapping for inbound connections but my old linksys wireless router i could apply access rules to these. For example I might only want a certain class C address range to access a inbound port 80 rule. So only these clients can access my internal web server.
Is this possible with the TC?

Many Thanks All

 

I can't wire the iphone and dell laptop very well. Also the TC only has 3 ethernet sockets and i've used these for a media streamer, home server etc
