[Winpcap-users] the ip address of the packets

[Prasanna Kumar Nelam]

Hello,

 

This is Prasanna kumar, I am working on winpcap library to capture the http
packets.

I have the doubt regarding packet ip address at the gateway. The scenario is
like

we have the LAN, and one gateway to provide the internet to total LAN.

If I run the Winpcap application at one end system, EX: if I send http
request to google, then the client ip address is my end system ip address
and server ip address is google ip address.

If I run the application at gateway and I raise the same http request from
the end system, then client ip address is gateway public ip address and the
server address is same, I am not getting end system ip address.

Is there any reason to happen like this, Or any bug in my code, I am running
the winpcap in promisious mode.  please help me in this issue.

 

Thanks in advance.
