[kolucoms6]

Here is the Situation :

I have 10 computers and all in LAN.

C1,C2,C3,C54,C5,C6,C7,C8,C9,C10

All computers , except 3 computers(C5,C8,C9) , are getting Broadband Internet through second Lan Card.

(C5,C8,C9) do have second lan card.

Now, I want

C5 to share internet with C1
C8 to share internet with C10
C9 to share internet with C2

Kindly guide me

well man i m no good at this ...
jus trying..
assuming you are using win XP

in your lan card under TCP/IP settings in the "Preferred DNS server"
for C5 put the IP address of C1
for C8 put the IP address of C10
for C9 put the IP address of C2 ...

i dont know whether this wud work ... i have never networked more than 2 PCs ...

Only DNS will do ?

No IP Required ?

well yes .. u will need to assign each of the computers an IP address...
i m not sure whether it will be assigned a dynamic IP...
make sure the computers are in the same domain/workgroup

I have 10 computers and all in LAN.

C1,C2,C3,C54,C5,C6,C7,C8,C9,C10
No SERVER.

C1: 172.16.0.1
C2: 172.16.0.2

and Like wise.

As in DNS server setting,

C5 as 172.16.0.1
C8 as 172.16.0.10
C9 as 172.16.0.2

Right ?

and How to make it shared for Internet ?

means, how C5 will get Internet from C1 ?

Do I need to install some Proxy server on C1 ?

in your first post ...
u have said "(C5,C8,C9) do have second lan card."

did u mean to say ... "do have second lan card." OR "do NOT have second lan card."

are you using simple cross wire cable to connect each computer with the next??

As in DNS server setting,

C5 as 172.16.0.1
C8 as 172.16.0.10
C9 as 172.16.0.2

Right ?

this looks correct ... u will need to make your broadband internet connection a shared one (jus as you share files and folders). now your windows firewall mite create issues in file and internet sharing. try disabling them within your LAN and try if you are able to share internet the way you want.
