Can't access several websites after last security update
Hello,
After upgrading both my Macbook Air mid 2011 and iMac 2008 (with SSD) both running Mountain Lion 10.8.4 to the last security fix, I can't access from any of those two computers a variety of websites, for example:
www.opennicproject.org
www.gentoo-el.org
www.adslgr.com
These are only three. Almost half of Google's results are blocked. Using the terminal utility I am able to resolv some of them but not actually 'ping' them. I get no ping replies. I can access all these websites from other computers or devices (iPhone/iPad/Ubuntu desktop/WindowsXP laptop) on the same LAN. This problem exists only in the 2 macs which are up-to-date. I am sure that this problem is related to latest security update I did a couple of days ago, to both computers.
I'd like to know if anyone who have all patches installed up to the latest OSX version (mountain lion 10.8.4) has the same issues and can ping/resolv/access these websites.
Note that although I can't access these websites directly using any direct network connection, I can access them using TOR browser bundle for mac, which means that something is going on at a computer level.
I have checked so far:
- Applicationn Apple's firewall is not creating the problem (disabled/enabled all)
- ipfw/PF is not running with any ruleset
- LittleSnitch blocks just a couple of annoying outgoing connections. Nothing there (I disabled/enabeld it, same thing).
- Other computers access the websites/ping them/etc.
- I can access websites using TOR.
NOTE: It's not just 3 websites, it's something like 1 out of 3 DuckDuckGo links.
Ideas and thoughts are welcomed!
Best Regards,
