You do not need a entry in local hosts file. If you use internal DNS, just place a Host(A) record for the cag. I guess the reason for this is that you want to use the same fqdn local as on the internet for remote connecting users. Though, if using DNS'es outside your control, you need hosts file entrys.

Thanks knew it was along that line - Still a bit confused - I zone transfer my internet zone - from isp to my internal DNS server - so internet lookup for our external dns is done local. In that external DNS zone I do have a host entry for cag - but it maps to the dmz interface of the cag. Why is this not sufficient - it must be working for external users? - but internal users need the internal interface (internal private IP) of the cag mapped to the FQDN (which is in an external zone - ie

What happens if you mannualy create at record in your internal DNS pointing the same fqdn to the internal IP-adress of the CAG? Dont really know if you can get your own recort to take precedence over the transfered record.  But, if it does, this should work for you.
