[clug] LAN

Hi All,

I was wondering if some could give me some suggestions on my home network.

I have a;

* N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700v2 

* and 9 computers (4 are R Pis lol), all running a Debian or Ubuntu based distro, except for two running Mountain Lion (I would like to get rid of Mountain Lion for GNU/Linux, but I am not sure if the drivers, fans, temperature, efi etc will be ok).

I am thinking that static ip addresses for the computers would be best as my aim is to;

* Use ssh to perform parallel mathematical simulations (like mpi)

However, I want the ssh to only work inside the LAN with a safe key as security is important (no WAN access).

My network looks like:

Router ---> 8 port switch -------> computer 1
                         |-------> computer 2
			 |-------> computer 3
                         |-------> computer 4
                         |-------> computer 5
                         |-------> 5 Port Switch ---------> R Pi 1
                                                |---------> R Pi 2
                                                |---------> R Pi 3
                                                |---------> R Pi 4

Any suggestions would be greatly appreciated as I am really not sure the best way to do this.

I have some knowledge of GNU/Linux iptables and freeBSD pf firewall rulesets.
I was thinking of making my own router using a computer with two ether connections, and putting it in-between my NETGEAR router and my LAN, but this seems complex for a noob like me.
