Hi guys! This is my first post

I have installed Joomla 3 on Server 2008 R2 on ISS 7.5 and able to access the site through the internal IP but unable to access it through the external IP.

I have ports 80 and 21 open and forwarded (confirmed).

Also firewall is allowing all incoming connections through port 80 (not outgoing).

I have a DNS Server installed (not sure if configured properly)

I have allow Full control for the CREATOR OWNER for the joomla directory

Where should I start?

anyone?

What error do you get?

In addition to needing the Error ("The page cannot be displayed"?)...

I have installed Joomla 3 on Server 2008 R2 on ISS IIS 7.5 and able to access the site through the internal IP but unable to access it through the external IP. <--Router/Modem?

I have ports 80 and 21 open and forwarded (confirmed). <-(see above)

Also firewall is allowing all incoming connections through port 80 (not outgoing).

I have a DNS Server installed (not sure if configured properly) <--Why installed?

I have allow Full control for the CREATOR OWNER for the joomla directory <--Have you allowed "Anonymous" in IIS Website (Internet Guest Account)?

Where should I start?

Should have been simple (other than IF you are using a Router). Sounds like maybe the Modem/Router is blocking. Mine allowed External IF it was from an External (not on my network) PC, but I had to change my Modem/Router for INTERNAL (when using e.g. No-IP Domain Name).
