You need to be careful if you use only IP to filter requests as this could be spoofed by a hacker. You should also use authentication if this needs to be secure.

Intercept the request at the IIS level by setting a rule to only allow a speicific IP address to access your service. You can find this under IIS > [Site/Service Name] > Properties > Directory Security Tab > IP addresses and Domain Name restrictions.

You could just run a check in each of your Webmethods that the clients IP is correct but as others have said an IP can be spoofed or subject to change so implementing authentication using WSE3.0 may be a better option.

[WebMethod]
public void DoSomething()
{
  if(HttpContext.Current.Request.UserHostAddress == "allowed ip")
  {
    //Your code here
  }
  else
  {
    //Access Denied
  }
}
