SmtpClient smtp = new SmtpClient("192.168.1.2",Convert.ToInt32(25));
yeal,you use the 25 port.you can have a try 465 or 587 instead. Search GOOGLE get the Gmail's default port

It can be because of various reasons. You need to look at them one by one.
Is the port open? Firewall permissions in place?
Further make sure you have configured SMTP configuration in Web.Config:

<system.net>
   <mailSettings>
     <smtp from="abc@somedomain.com">
       <network host="somesmtpserver" port="25" userName="name" password="pass" defaultCredentials="true" />
     </smtp>
   </mailSettings>
</system.net>
