Hi, we have installedexchange server 2007 behind Fortigate 60B firewall. How to publish OWA behind the firewall can anyone help us to do the same. Regards, Nzm

You only need to pass outside traffic to port 80 and 443 to your internal exchange server.

Thanks for the reply. We'll try the same. Nzm

Dear I have same question but little bit different actually i am using trend micro IMSS for spam filtering. now after installing IMSS we mapped email external IP to system having IMSS whereas exchange is on other server which IMSS deliver to Exchange. but OWA website is on exchange system and firewall is pointing to IMSS system so the reason my OWA is not working. how can i map OWA in firewall to Exchange system keeping forwarding to IMSS system. hope you could understand the situtaion. Thanks
