Hi Michael, Can you use Tom Shinder's article available at: http://www.isaserver.org/shinder/tutorials/vpn_back_to_back_isa_server_envir onment.htm <http://www.isaserver.org/shinder/tutorials/vpn_back_to_back_isa_server_envi ronment.htm> I used it and everything worked out fine. Best Wishes, Julius Orayo IT Manager, Medical Express Tanzania. -----Original Message----- From: Mike Anderson [mailto:manderson@xxxxxxxxxxxxxxxxxxx] Sent: Saturday, February 02, 2002 2:42 AM To: [ISAserver.org Discussion List] Subject: [isalist] VPN access http://www.ISAserver.org I am trying to set up an office to connect to my network through a VPN connection. I have everything set up with ISA and my firewall, but when I try to connect from their network, I get an error when the authentication comes up. I know the username and password/domain info is correct, what I am assuming is that their firewall is blocking the response from my firewall. If anyone knows what ports I need to tell them to open so that the connection can complete, I would appreciate the info. If it is in Tom's book, could you point me to the right chapter/page. I have looked but haven't found what I need yet. Thank you, Michael Anderson, MCSE Network Administrator Bonneville County ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jorayo@xxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
