I have a exchange server sbs.abc.local running exchnage mail
I have domain name abc.com
mail MX is pointing to my public ip address 2xx.1xx.2xx.1xx
my internal ip address of server is 192.168.0.1
if i ping mail.abc.com from inside network i get publice ipaddress resolved 2xx.1xx.2xx.1xx
if, from outside our network (from home) i go to mail.abc.com/exchnage i get my OWA and i can log in and it works
If I try and goto to the same address (mail.abc.com/exchnage) from work I get a error from router.
I there some entry to the DNS server running on our 2003 SBS server or in the router that will point any computer on the internal network useing our DNS server to resolve mail.abc.com -> 192.168.0.1 (sbs server)
