Can't open gmail, hotmail, ebay, etc... help needed

Hi guys, I can’t seem to be able to to open this websites, at first I thought it could be the SSL but it’s not , unless only SSL enabled webpages from my country work ( I can use SSL webpages in my country with no problems ). Unless the websites in my country aren’t really using SSL.

I tried lowering the MTU (I have a PPoE connection here ), and If I lower it to 300 , ( I know that’s insane ) , gmail works. I have searched the forums and some other ppl did also have the problem.

I am trying to access gmail with no Firewall rules at all, it’s a very simple setup , I even formated my router and tried again with no luck :frowning:, using version 2.9

What are you using for DNS?
