    UDP based packet transmission problem?

    I have simple udp client and server using UdpClient class in .net frame work 2.0
    My Ip address is 192.168.5.20
    and client ip address is 192.168.1.25 and we client pc and mine are on same network
    When i tried to send udp packet from client to server exception occurs: "A socket operation was attempted to an unreachale host 192.168.5.20:10 080..."
    But when i change my(server) IP address to "192.168.1.20" communication is fine.
    How i can solve this problem or,how i can send packets other than my domains ip addresses.

          Dude... You posted your question at 00:38 hours, then plead for help 4 and a half hours later at 5am. Give people a chance to wake up in the morning and have a cup of coffee.

              Because you are working inside a private network range, you may be bumping up against filtering behavior from your switch/router.

              Many routers do not let traffic from the 192.168.1.x range go outside of itself. Are the two computers on the same router?

                  re

                  Thanks, for your reply and suggestion
                  both computers are on same network, the application where i am developing here are only 3 computers attached with switch.
                  and where i have to implement this there is no router(small network).
