any answer please? 
by the way, I've just found iptables package here:
http://maemo.org/packages/view/iptables/
Can I just use it?
Which one should I download?
And do I just install the deb file?

Hi,
Can anyone tell me how to install iptables firewall on N900?
As far as I am aware, the default kernel is not compatible with iptables, or is it?
If it's not, how do I install both the compatible kernel and the iptables itself?
you would need to compile your own kernel and put it in an image and flash the device with it I believe. Not ure if you cn recompile kernel on device, but I doubt it

I've found some posts which are related to my question but since I am new to Linux I still couldn't understand how to install them

Also, if the default kernel of N900 is not compatible with iptables and if I do a firmware up'grade on my N900, will the compatible kernel got replaced so that I will have to reinstall it again?

Thank you in advance.
P.S.: If there's something wrong with what I said, please correct me since I'm not sure if I understood those things properly. All I want is a firewall

Thank you for your answer. 
By the way, can I just use the package here and how do I use it?:
http://maemo.org/packages/view/iptables/
The explanation says that:
Does this mean that it includes the kernel?

The explanation says that:
"These are the user-space administration tools for the Linux kernel's netfilter and iptables."

There is sshd available and working for N900.

I still need some help on iptables though

Also discussed in this thread.
I'm still not 100% sure you cannot not do very basic iptables (setting input policy to drop for example) with the stock kernel.
I have not tried it and I'm running a custom kernel because I'm developing a mobile hotspot.
Compiling a new kernel (or just modules in case they do not require any special/extended symbols in the kernel proper, but netfilter does...) is not really that hard once you have a working scratchbox (see for example the bottom of the hotspot project page).
There is also kernel-maemo which is a (separate) custom kernel with even more features than the hotspot one (which basically adds only netfilter and qos).
As for "sshd available and working" only if you explicitly install it.

All I want is to block all incoming connection and block unused outgoing ports, allowing only outgoing ports that I use.
