We are using a Checkpoint firewall and have recently installed MS Exchange 5.5. I am trying to set up an Outlook client to access the Exchange server through vpn. Is this possible? What do I need to do to on the Exchange server to achieve this? This is a managed firewall so I wouldn't be the one to adjust or create a rule if that is what's necessary. The clients would be utilizing some version of Outlook. I have VPN'd successfully to other resources within the LAN. Any help is greatly appreciated!
