ISA Server Web Publishing an OWA through a Checkpoint Firewall-1. I've got an ISA Server installed in Cache Mode and a Checkpoint Firewall (NG). My configuration is: Clients/Exchange 2K -> Isa Server -> Checkpoint -> Internet I configured the ISA to Web Publish the Outlook Web Access (OWA) of my Exchange 2000 (SP2). I saw that the web publish of the OWA is working fine. I opened my Checkpoint to the ISA WebPublish (Port:80), But it doesn't work, Please tell me how to configure the Checkpoint or the ISA so it will work. Thanks Roni Assa. ronia@xxxxxxxxxx
