I've updated to Mountain Lion, and I'm having some DNS problems. I always PPTP/L2TP VPN connections on my macbook. Recently after a while of working with Mountain Lion, VPN stops sending and receiving data and I have to disconnect/connect again to make it work again. I'm not having the same problem with iPad, iPhone and PC.

and without the VPN, when I try pinging , and other DNSs and all I get is timeouts! But the ping works fine on my other devices. I also tried setting the DNS to Google and OpenDNS DNSs (,,, ...) but it still didn't help. I also tried emptying DNS cache and other solutions. but nothing.

I'm guessing that these two problems are tied together. Any solutions?



change the primary DNS to your local gateway address, like or I have the same problem in PC, try it, It may be useful ;)

  • In Mac OS it is set to local gateway by default if you don't provide any other DNS. So that's not the case – Sallar Aug 21 '12 at 18:26

in windows too but set it manually, and use the "" in secondary DNS server... if u have this Problem without VPN, use one of these DNSs : or use the "namebench" software to find best local DNS server for u... ;)


Updating to OS X 10.8.1 fixed the bug.
