[twsocket] UDP SendTo() sends two packets?

I have the code to listen on a UDP port when the first button is clicked, and send a packet when the second button is clicked. It works fine except when the second button is clicked, it sends two packets (I captured that with Ethereal.) Is there anything I'm not doing right? -- Best regards, Jack

Re: [twsocket] Requesting an Ephemeral Port

Actually all I need is just to make windows ignore any tcp/udp traffic at a range of ports (eg : 3 - 4). Does Winsock have any facility to do this? The only solution I thought about right now is disabling TCP/IP on the LAN adapter that connected to Internet(WAN). I receive all the pack

Re: [twsocket] Requesting an Ephemeral Port

I think the original packets wasn't sent out because my LAN interface in the NAT Server device doesn't have any gateway attached... But I'm not really sure... I'll try to sniff it later... On 5/2/06, Jack <[EMAIL PROTECTED]> wrote: > > Hello Widita, > > To my knowledge, Windows raw sockets let y

Re: [twsocket] Requesting an Ephemeral Port

Hello Widita, To my knowledge, Windows raw sockets let you capture packets and create new packets, but I don't think you can change or drop packets. Are you sure the original packets wasn't sent out? -- Best regards, Jack Tuesday, May 2, 2006, 8:34:30 AM, you wrote: > Right now i can receive a

Right now i can receive any incoming packets, edit those which need to be translated, and send it to the internet, but when the reply came to my mapped port on the NAT machine, Windows automatically sends a TCP Packet containing RST flag to the replier... On 5/2/06, Fastream Technologies <[EMAI
