DNS Port Forwarding

Hello Experts,

I am trying to get my DNS correctly configured. My internal domain name is domain.local. We recently moved our exchange from being internally hosted, to having it hosted by an outside company. My email is domain.org as well as our website domain.org.  

Here is what I have done thus far.  I created another zone on my DNS server using Split-Brain DNS.  So now on my server I have domain.local and domain.org. Everything is still working and my network is not broken. The problem I am having is when users try to access the domain.org website it will not display. External users outside can reach the website so I know its an internal issue.  

My confusion comes when I try to point internal users who want to go to the website.  Do I need to configure this on my DNS server or do I need to look at configuring this on my Cisco ASA device?

Thanks for any help you can provide.

You need to configure names (A records) in your internal DNS that point to outside addresses
for each related service like:
www.domain.org for website
mail.domain.org for email
webmail.domain.org for webmail
etc.

Add a www A record internally in your domain.org zone and point it to the IP address of your website.

Setup any other DNS records that you have externally, internally in the domain.org zone and you should be fine.

in internal domain.local  A host abviously pointing to local dns
as well what you created the another zone  domain.org
in this zone create a A host record point it to your web site ip address

before go for it... the local domain should ping your website...

all the best
In the split dns configuration you've to create the same dns records as present in the external dns eg:  owa,mx,ftp, with public ip.
