        Hi Varga,
        What services do you want to access from the external Outlook
client? What version of Outlook are you using?

                        Hi all, 
                        please, how to configure firewall (which is not
in domain) and Exchange 2k Server (with internal IP) to allow external
client access to their mailboxes?

                        I have already set: 
                        Exchange 2k Server 
                        - Active
Directory\Users\Properties\Dial-in\Remote Access Permission (Dial-in or
VPN)\Allow access & No Callback

                        ISA Server (firewall & proxy server, not in a
                        - Access Policy: 
                                Mail wizard rule SMTP, SMTPs 
                                outgoing smtp, pop3, imap4 
                                ssh, imcp, dns 
                                + IP Packet filters VPN (PPTP, L2TP),

                        I was trying also to configure Outlook account
with external IP of firewall = Outlook could not logon. 
                        Is VPN configuring both client and servers only
way to resolve it? And how? 

                        Thank for any advice.
