guys m trying to connect my pc with other two pc in my bldg but faced with the foll. problem:

1. There r three pc's which i am trying to interconnect. Lets say PC1 , PC2 and PC3.
2. PC1 has one lan card while PC2 & PC3 have 2 lan cards.
3. Each pc has its own modem and internet connection.
4. I have kept a dlink 8 port switch at my place i.e PC1.
5. since i have (pc1) only 1 lan card, i have connected my modem and pc to the switch.That means i m accessing internet not directly through modem but with switch.
6. PC2 connects to the internet using its own modem using one lan card and the other lan card is used to connect to the switch.
7. PC3- same as point no. 6.
8. since both PC2 & 3 connects to the switch, i make sure that they dnt access my internet.
9. In this way i can see( i.e pc1) both the other pcs in my network places.
10. pc2 and pc3 can see pc1 but not each other. WHY??

i hope its not confusing. so solve the problem reg point no. 10
 
What you will need to do is set up three Class C Networks.

192.168.1.1/24 - Use this network for the modem of PC1

192.168.2.1/24 - Use this network for the modem of PC2

192.168.3.1/24 - Use this network for the modem of PC3

192.168.1.2/24 - Use this network for the lan1 of PC1

192.168.1.3/24 - Use this network for the lan1 of PC2

192.168.1.4/24 - Use this network for the lan1 of PC3

192.168.2.2/24 - Use this network for the lan2 of PC2

192.168.3.2/24 - Use this network for the lan2 of PC3

This should solve all ur issues. BTW /24 = 255.255.255.0 (subnet mask)
 
thnx for the reply , but u ddnt understand the query. Ill rephrase the question:

Since we all have our own internet connection, wat i want is just the local connectivity between our respective pcs. I thnk its not possible w/o using another lan card in my pc.
