doubt on default gateway

tj123

hi...

i have a doubt about the configuring of the default gateway in the tcp/ip settings on a computer connected to LAN

consider 4 computers in a LAN.....i.e C1,C2,C3,C4 with MAC adres A,B,C,D respectively

C1 and C2 are in the same n/w with ip 192.168.1.1 & 1.2

C3 and C4 are in the same n/w with ip 192.168.10.1 & 10.2

now i wanted to ping C4 from C1
For this i set the default gateway of C1 with IP of C2 which is in the same n/w of C1
and that of C4 with IP of C3 which is in the same n/w of C4

now i pinged C4 frm C1.... but the result was
request timed out

bt when i checkd the arp table of both C2 and C3 which acted as the default gateway , both had the mac adress of C1 and C4 i.e A,D

can u help me why C1 and C4 did not communicate eventhough their default gateways had the MAC adress of C1 and C2

thanks

Computers can't communicate with each other unless they're on the same network, or they have a gateway that is connected to the other network in some way. Assuming you're using a subnet mask of 255.255.255.0 and each computer only has one network card, I can't see a way to make your situation work without the use of a router.

Someone with more networking knowledge than myself may be able to help you more.
