This is useful when you´ve created you've configured your account and set up the Amahi-serverwith an internal domain that matches an external domain. You are asked If you chose to disable your previous router DHCP. Now , Amahi is running the DHCP and the DNS-services of in your network. If you already have an external URL with the same name as yourhda.com then you will probably run in to some problems reaching those external services like mail and www-sites

The easiest way If you want to fix this is to create an alias for access a URL (or in general any host) '''outside'' with the external URL and "punch a hole same domain that you have in the internal network, the local DNS-server"may not let you, as it will resolve locally (or not).

Go The easiest way to fix this is to create an alias for the external URL and effectively "punch a hole in the local DNS-server." To do that, go to http://hda/setup?sub=2&tab=network

* Fill in alias: the service you want to reach on your external URL, but only the first part, e.g. "mail" or "www"* In the Ip-adress IP address field , fill in the external IP-adress address for your external URLhostname. (the four sets of numbers with dots inbetweenin between, e.g. 12.23.34.45)

That would do the trick (at least it did for me)local DNS resolve that alias to the external IP address.
