Allow VPN Branches Access OWA - 29.Sep.2007 4:01:44 PM

Hi!

I need help allowing my VPN Branches access OWA. I can ping my ISA Server's External Interface from my branches and they can connect to my isa server by dialing a vpn connection but since i have Cisco VPN routers in branches and they can ping my ISA Server External Interface even without connecting the vpn connection, they should also be able to access OWA.

1. My ISA SERVER has a Public IP.
2. Exchange Server is Published and my users can access OWA through Internet.
3. Branches have private ip ranges: 192.168.2.1, 192.168.3.1
4. ISA SERVER Internal IP is 192.168.1.1
5. Exchange Server IP is 192.168.1.8

Thankx!

Do you want the branch office users to connect to OWA over the site to site VPN link, or other the Internet?

Thanks!
Tom

Thanks for the reply. They can access OWA by the published IP and not by its URL. This may be because they don't have internet access. They are connected through a VPN Tunnel of Cisco Routers with private IP ranges through my ISP. The only thing is that they are unable to use Outlook Anywhere even after importing the certificate into their Computers. I tried to use the internal IP of my Exchange Server and also the public ip of ISA where exchange is published in Outlook's http connection settings but nothing worked.

If they connect from Internet then no problem.

Thanks!

Is there a Network Rule connecting the source and destination Networks?

Thanks!
Tom
