I'm very new to ISA (and this excellent list as well) but I want to learn everything! The problem I'm having is that I can't seem to get my Unix (HP-Ux 10.20) clients to send/receive email through the ISA server (integrated mode) I have set up at the office. The Windows 2000 clients have no problem with email as they can use the Firewall Client without any problems. Normal webpage viewing using ISA as proxy is no problem on any system, and works like a charm. The Unix clients use Netscape's mail client, but that shouldn't be a problem. We currently have no internal mailservers, so I want to have my clients to connect directly to the POP3 and SMTP servers at our ISP through the ISA server (which has DSL hooked up to it). The clients have the ISA server as their gateway, and the ISP's DNS servers for DNS. I have been reading up on SecureNAT for a while, and think I have followed all instructions on ISAserver.org to get it working, but without any luck. Is it possible to have my clients (both Windows using Outlook XP, and Unix using Netscape Mail) access the POP3 and SMPT servers through SecureNAT? For the Windows clients I could use the Firewall Client, but if not needed I wouldn't mind not doing it. Is there a good way I can use to verify that SecureNAT is working properly? Please help me out, as I really want to get ISA server working properly so I can convince my managers to use for the entire company.
