Firewall question, from LAN using destination NAT

RouterOS General
1

I’m using a Routerboard 450G with 4.1. I’m using this as a firewall. I started with the Firewall examples from the Wiki and it’s working good. I also Have a few port forwards to an inside server using destination NAT.
So I’ve for example http://www.examplecompanytest.com which is a CName of the public IP of the Mikrotik, using destination NAT all tcp 80 (http) traffic is going to a inside server.
So faw so good.

But when my LAN users go to http://www.examplecompanytest.com it’s not working, they are getting a connection refused. Can somebody point me in the right direction ?

Search for ‘split horizon DNS’ and ‘hairpin NAT’.

not ‘split horizon’, but ‘split DNS’ or ‘multi-view DNS’ =)

A google search for ‘split view DNS’ brings up the Wikipedia ‘split horizon DNS’ article as the second hit. It’s all the same thing; provide a different DNS reply depending on where the reply comes from and serve inside clients the inside IP, and outside clients the outside IP.
