If your DNS settings are specified by DHCP, check your DNS settings both before you connect to the VPN and while you are connected. You should set up your computer to use a free public DNS server (see How to use a different DNS server, below) while the VPN is active. 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. If the manual DNS server is your ISP's DNS server, it is probably set up to ignore queries that come from outside the network. If they do, that server will be used even when the VPN is active unless you put a check in "Allow changes to manually-set network settings" on Tunnelblick's "Advanced" settings page. See if your network settings manually specify a DNS server.
If you don't have a DNS problem then there is something else going on. (Consider the IP address to be "working" if any of the webpage loads.) If the IP address works, but the name doesn't, there is a DNS problem. To check that, try to access a website by using its IP address instead of its name. Tunnelblick includes the ability to diagnose some DNS problems and will warn you about some common configuration problems.Ĭheck for a DNS problem: If OpenVPN connected to the server properly, but you are having trouble connecting to websites, the first thing to find out is if there is a DNS problem. If OpenVPN is connected to the server but you can't access the InternetĪfter connecting, if you can't reach the Internet, it's likely that your setup has If not, or if you aren't sure, look at Common Problems. This page assumes that you are successfully connected to a VPN server. This guide is meant for the most common setups, so if it doesn't apply to your situation, or doesn't help, see the Support page for guidance. OpenVPN is such a powerful tool with so many options, and computer configurations are so varied, that it is impossible to have an exhaustive troubleshooting guide. If one way or the other solves your problem, you're done! Troubleshooting this problem could be very simple: try connecting the VPN with and without "Set nameserver" selected.
If OpenVPN is connected to the server but your IP address does not change Use a different DNS server only when the VPN is active Use a different DNS server whether or not a VPN is active If OpenVPN is connected to the server but you can't access the Internet
