Hi I have installed 3 homed ISA server. I published my internal Exchange 2000 server.it is working fine. I am facing problem publishing IIS (OWA) in server. I have given Additional Public IP Addr to external interface of ISA server. And using the second public ip i published the mail server. In my DNS server which is in DMZ I put ALIAS entries points to public ip of the mail server. In my internal exchange server I tried by putting both internal and public IP (which I published) for IIS but mail.ourdomain.com is not working. DNS etries are proper b'z it was working without firewall. I used web publishing to redirect all the request to the internal ip for that particular public IP . But still not working. Anyone can help me on this ? Regards Aboo Arif
