      I am having one that has me scratching my head a bit.

      Here is the setup:
      Box 1 IPs Internal 10.0.1.4 - External x.x.x.x
      Box 2 IPs Internal 10.0.1.5 - External x.x.x.y
      Box 3 IP Internal 10.0.1.6

      External IPs are 1:1 NAT to internal IPs and have no trouble reaching the broader internet

      Box 1 hosts a website call it http://www.testsite.com

      When Box 2 or Box 3 try to reach any other website, there is no issue.

      When Box 2 or Box 3 try to reach http://www.testsite.com they cannot pass any traffic if using the URL. If they use the internal 10.0.1.4 IP address, they can reach the machine no problem.

      Any idea how to go about fixing this?
