I have primary site with domain: abc.mail.lan at ohio.
and one other AD site at Dayton as also domain.lan , I used OWA worked fine inside my office and outside my office that is at home for both these sites which are having forest relationship.
our squid proxy behind the firewall handles all the owa traffic which had hardcoded IP address to our exchange server which is at primary site.
but the other AD sites are having child -domain relationship with primary site from sites like phx.abc-mail.lan
when I used OWA using user mail box of one of the other AD sites like one is in phoenix internally from my primary site I can connect from inside to other AD sites from my primary AD site - but cant from home to those same AD sites which are having child domain relationship.
my question is:
If I connect to one of their AD sites through RDP from my office at primary AD site and do nslookup when on their exchange server to our owa address I get the proxy server ip reply.so how it is connecting internally in office fine and not from home
AD sites having forest relationship -owa works fine internally in office and outside office using same OWA URL defined in proxy squid server
AD Sites having child relationship -owa works fine internally in office but not from home.
do I need to create separate A record for those other AD sites like phy.abc-mail.lan /owa in my squid proxy server?
