Timeout on Load

Hello Everyone,

This is my first time to configure Mikrotik Router using v3.1 . My ISP gave me 12 IPs x.x.x.203/24 and I want every client have different IP everytime they search on google to avoid the captcha saving our time from typing those letters. I added all IPs on addresses via winbox. And yes every client has different IP but my problem now is that Everynow and the pages are timed out and failed to load. We can’t also send mails in Gmail and other mails.

Here are the steps I made but failed to achieve my goals.

I created a nat srcnat=x.x.x.0/24 and action-srcnat = x.x.x.203 - x.x.x.214 (which is provided by my isp).

Can anyone help me resolve the problems?
