Publishing Groupwise server through ISA 2000 Firewall
Posted on 2004-08-09
Anyone done this or know how? I can't find much help either on novell.com or isaserver.org.
I've done the Secure Mail Server publishing on ISA, opening up port 25 inbound and outbound to the internal groupwise server (10.5.1.5). The external is NATed on 192.168.1.5 which is an IP bound to the external NIC on the ISA server.
The 192.168.x.x addresses are in our DMZ. Then we go "outside" through a Checkpoint Firewall.
Telnetting to 192.168.1.5 25 from a machine in the DMZ, it seems to connect, but it never has a "welcome/ready" response, the screen is just blank, and then it disconnects after about 15 seconds.
Running a netstat -na on the ISA server shows that 192.168.1.5 is listening on port 25.
Are there other ports I need to establish rules for to get Groupwise to work?
I've read TID10011226 and TID10054739 but still no luck....
