2. If OpenVPN is connected to the server but you can't access the Internet
If OpenVPN connected to the server properly, but yo u are having trouble connecting
to websites, the first thing to find out is if ther e is a DNS problem. To check that, try to
access a website by using its IP address instead of its name. For example, try
"
http://129.42.58.216
" instead of "
http://www.ibm.com
" or use some other, known IP
address. If the IP address works, but the name does n't, there is a DNS problem.
(Consider the IP address to be "working" if any of the webpage loads.)
If you have a DNS problem:
1. Make sure your network settings don't manually s pecify a DNS server. If so, it
will be used even when the VPN is active. If the ma nual DNS server is your
ISP's DNS server, it is probably set up to ignore q ueries that come from out-
side the network. When you are connected to the VPN, your queries come
from the VPN server, which is probably outside the ISP's network, so the ISP's
DNS server will ignore your request. You should set up your computer to use
a free public DNS server (see
How to use a different DNS server
).
2. If your DNS settings are specified by DHCP, chec k your DNS settings both be-
fore you connect to the VPN and while you are conne cted.
o If the DNS settings are the same, try setting up yo ur computer to use a
free public DNS server (see
How to use a different DNS server
).
o If the DNS settings are different, the VPN server h as successfully
"pushed" a DNS server to OpenVPN and that server is being used.
Contact the person who maintains your VPN server to find out why that
DNS server is not functioning properly.

If you don't have a DNS problem then there is something else going on. Ask the
Tunnelblick Discussion Group
for help.

How to check your DNS settings
1. Launch System Preferences,
2. Click "Network"
Your DNS server list is one of the entries on the r ight. It is a list of IP addresses,
separated by commas. OS X will use the first one un less it fails to respond to re-
quests, in which case it will try the second, then the third, etc.
Note: If the DNS server list is dimmed (grayed out), it was set via DHCP, not manu-
ally.

How to use a different DNS server
You can set your computer up to use a different DNS server.
Google Public DNS
is
free, and
OpenDNS
has a free version:
1. Launch System Preferences,
2. Click "Network"
3. Type "8.8.8.8, 8.8.4.4, 208.67.222.222, 208.67.2 20.220" (without the quotation
marks) into the box to the right of "DNS Server"
This will set up your computer to always (whether o r not you are connected to the
VPN) use two Google DNS servers and two OpenDNS ser vers (in that order).
