[fallout20xx]

Hi everyone,

First of all, I must recognice that this is my first pfsense installation.

I have 2 pfsense 2.3.3 sincroniced with virtual ip, 1 LAN and 1 WAN.
OpenVPN working.
LAN client work perfect with DHCP.

the problem it in the pfsense VM inself.
When I ping to 8.8.8.8 all perfect but if I try to ping to for example www.nba.com it do nothing. It says:
ping: cannot resolve www.nba.com: Host name lookup failure

Problem it's that I need to install the xen tools, and pkg is not working, I thing that it's for the same reason, but I cant find the problem.

Can anyone please help me?

@fallout20xx:

ping: cannot resolve www.nba.com: Host name lookup failure

This means you have to setup a DNS server for pfSense to resolve www.example.com to an IP.
