You need to open two types of traffic, the first that is pptp or port 1723, and the second is the protocol GRE, you need to specify that is protocol IP GRE not tcp or udp and no ports, now I'm searching the configs of my clients that I configured in the past with this configuration and now they are working fine. Remember that is not open ports, is publish the resource for redirect to the external ip of the ISA Server. ________________________________ From: Lian-Wee LOO [mailto:lwloo@xxxxxxx] Sent: Monday, April 05, 2004 11:02 AM To: [ISAserver.org Discussion List] Subject: [isalist] RE: Cisco Pix 535 http://www.ISAserver.org I am not sure, I don't think they will change. Anyway to resolve? What are the port need to be open in order for me to connect to ISA VPN server? It always stuck at the user authentication part, should be error 721. Please advice. Thank you... best regards, lwloo 2k'3 ________________________________ From: Thomas W Shinder [mailto:tshinder@xxxxxxxxxxx] Sent: Monday, April 05, 2004 8:29 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: Cisco Pix 535 http://www.ISAserver.org Hi Lian, Sounds like the PIX is misconfigured, which is a common problem. They might want to consider upgrading the PIX to ISA 2004.
