Re: block some PC on the network
hacking from where? within your own network of from the outside?
From the outside you close your ports you dont need.
As for banning from a partial IP.. yes.. some routers have you set it differently...
Like: 192.168.000.000 or 192.168.*.*
If your worried about people on the network hacking to get into the router and changing the ports so they can get around, then you may have an issue.. For this I would recommend:
Buy yourself a Gateway. (stronger then a router)
Buy yourself a switch.
connect the switch to the router, The switch will issue automatic IPs itself. You now only have to worry about 1 ip in the router from the switch.
You then would only have the computers on the network connecting to the swtich, all other internet users would connect to the router.
but your worried about the router issueing more ip?
if you tell your router to only issue 192.168.0.100 thru 192.168.0.106 then thats all the router will assign.. no one will be able to have 192.168.0.107
