Dear Sir, I have ISA server installed in Integrated mode and is directly connected to the internet. Behind this ISA server our company's Mailserver (Lotus Domino Rel 5.0.2) is working. I can easily send and receive mails over company's Local Area Network, but the problem is that when ever i try to access my mailserver through internet via Internet browser, my firewall doesn't seem to let me access my mailserver. I am not only unable to access my mailserver remotely by using HTTP protocol but i could not access it remotely via Lotus notes. I can easily access my mails when my mailserver is directly connected to the internet. Kindly do let me know that is there any way that i can solve this problem by opening some port or protocol.
