Hi all,
I have installed Microsoft Exchange 2003 in two locations, the two sites are connected with cisco routers (without NAT); The architecture contains replication between Microsoft domain controllers ...I can send and receive mails from and to the two sites. I have integrated Cisco PIXes (version 6.3(3), (with NAT 0 and Static for the same addresses) , the replication between the DC works very well but i can't send and receive emails from the two sites (i haven't restrictions: permit ip any any on the two pixes).*
I know that pix has problems with exchange, because exchange uses ESMTP so i disable the fixup smtp to not inspect it; but no function also.
The problem is in the return traffic from outside to inside ... there's no deny when debugging but just teardown...
Any help.
thanks.
