Question : lan
i have LAN of 15 computers,
i want only 10 of these computers have access to internet through my US Robitics Router,
so i want to control that in any way, making no ip can access except who i permit..,
here is the scenario:
i'm using 192.168.1.1 as my default gateway
ip rang from 0-254 so i'm using that (192.168.1.x and 192.168.1.y ...etc) with subnet mask 255.255.255.0
i'm using work group, there is no domain
so every body can put that configuration at his computer and then use the internet via my router,
so how i can decrease number of ips that allowed to access the internet???
Answer : lan
or if you want them to get out but just want to restrict their access to the internet to certain sites
Filtering Internet access
*****Method one******
Pro's EASY TO DO. CON's NOT GOOD FOR LOTS OF CLIENTS.
How you approach this depends on how many users you are talking about, if its just a few users, the simplest way is to modify the host file on each PC and put an entry in it for each domain you DONT want the users to access and point them to 127.0.0.1 (you can edit the hostile with notepad or this,
http://members.shaw.ca/tec
hcd/VB_Pro
jects/
Host
sFileReade
r.exe
For example to block
www.hotmail.com
add this line to the end of the host file.
127.0.0.1
www.hotmail.com
NB in win 95/98/ME the host file is at C:\windows\hosts.sam (save it WITHOUT the. Sam extension and reboot)
In windows 2000 the host file is at C:\winnt\system32\drivers\
etc\hosts (you can edit directly and NO reboot is required)
In Windows XP the host file is at C:\windows\system32\driver
s\etc\host
s (you can edit directly and NO reboot is required)
*****Method Two*****
Pro's Easy to administer. CON's Expensive & NOT PRACTICAL FOR HOME USERS.
Give all your clients access to the Internet via a Proxy Server than can filter and block websites.

*****Method Three*****
Pro's Very scalable from home user to businesses. CON's Can Be Expensive
Use some third party software to do it for you.
