I setup Virtualmin and setup my first Virtualhost:
I changed the WWW A Record to my ISP assigned IP addresss:
[REMOVED].com -> [REMOVED]
When I go to the url from an external device, I get page not found. I can access the virtualhost just fine through the local ip address.
http://www.intodns.com/[REMOVED].com Everything seems fine on this page.
[Edit: So far, seems like an issue with our ISP not allowing external access with dynamic IPs. Waiting for Static IPs now.
