hi
i installed Zimbra Email Server in my (DMZ) 192.168.5.0/24 , my server ip 192.168.5.5 , and i have internal network 192.168.1.0/24 . i can not connect to my zimbra mail server using (Zimbra Desktop) , i got this message:
service.FAILURE: system failure: error while proxying request to target server: HTTP/1.1 407 Proxy Authentication Required ( Forefront TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )
any one can help me how to do the authentication for my users
my TMG server joined to my domain.com int (192.168.1.0/24) , and i used my domain users to connect through my proxy. but it seemed something wrong in my TMG.
i need my clients in internal network 192.168.1.x to access the Zimbra Server in DMZ 192.168.5.x , i can ping the Server 192.168.5.5 and i can access the mail web app , but i can not access it using Zimbra Desktop (mail Client app), where i allowed all protocols in my rule !!?.
Best Regards
