Dear Spammers,

Thanks for waking everyone on the list up last night. ;)

Dear List,

Now that you're all awake, and following the number of requests for some 
technical discussion, here's my current challenge on my little research 
project...

Yes, I'm wanting to figure out the following for a Mikrotik RB750G 
router, but AIUI the mkt runs a Linux core, so my request is on topic ;)

I've got a number of networks on my router....

192.168.1.0/24
192.168.2.0/24
192.168.3.0/24
192.168.4.0/24

192.168.1.2 can ping 192.168.2.2, 192.168.3.2, 192.168.4.2

That's cool.

However I don't want people on 2.0 to be able to see computers in 3.0 or 
4.0, etc.

I also don't want them to be able to establish windows networking 
connections -- so basically samba/smb connections.

However I do what 192.168.2.0/24, 192.168.3.0/24, 192.168.4.0/24 to be 
able to use a NAS in 192.168.1.0/24.

So I need to drop some traffic unless it's heading to my NAS IP 
(192.168.1.2 for sake of argument).

I do want users in 192.168.x.0/24 to be able to see each other though.

I'm using a Mikrotik 750G with router OS5 on it, lic 4.

TIA


D
