FIX OSX Lion Not Resolving DNS Addresses Over VPN

Problem: While connected to VPN, I was not able to resolve hostnames on the remote site.

Solution: Create a domain resolver file in /etc/resolver named for your domain, for example:

sudo mkdir /etc/resolver

vi /etc/resolver/yourdomain.com

Add the following content and save the file:

nameserver x.x.x.x <- your DNS server to resolve hosts on this domain
domain yourdomain.com
port 53

You can create as much as needed custom domain resolver files, one for each domain.
