External connect exchange 2k3 problem

HI

I am new user and setup Astaro Security Gateway V7 testing.

Masquerading rule:
Internal->External

Internal can get internet access. But MS outlook can not connect external Exchange Server(  through exchange https proxy login).

I try add rule in packet filter: 
exch->any->internal
internal->any->exch

also can not connect.I think it is exchange https problem,but how can i fix it?

Thanks

  • I checked Packet filter log. 
    PC:51332 ---> external Exchange:445--------------------allow
    PC:51332 ---> external Exchange:135--------------------allow

    But Outlook also show disconnect. I think it may be login problem. I stopped Http/s,http scanning and Intrusion Prevention.also can not.

    I bypass astaro firewall,Outlook can connect exchange.

    Who can help me please~
