I have enabled the passthrough. I have also set up IPv4 rules for IPSEC-UDP-ENCAP and IKE to go to my server.  At home I get a 720 error code every time I try to connect. Any suggestions will be apreciated.

From further investigation, I can not ger port 1701 to open on the SA. I made the rule but the scan show the port is not open.

Hi Guy,


Error code 720 means that a connection to the remote server could not be establised.  Microsoft's Support pages for PPTP and L2TP hint that there may be a misconfiguration of protocols between the Server and Client machine.  Please see following troubleshooting articles.

To setup the SA 500 series device to allow PPTP  connections to pass through, you have to have PPTP passthrough enabled (checked) on the VPN ->IPSec  ->Passthrough web page of the SA 500 Security Appliance Configuration Utility.  Also, you must create a firewall rule to allow PPTP service to be forwarded from the WAN to the IP address of your 2003 server.


For the case of L2TP, you have to have  IPSec and L2TP passthrough enabled (checked) on the VPN  ->IPSec  ->Passthrough web page of the SA 500 Security Appliance Configuration  Utility.  Also, you must create firewall rules to allow IKE and IPSEC-UDP-ENCAP services  to be forwarded from the WAN to the IP address of your 2003 server.


I hope this helps you on your way to configuring your remote access.


Cheers,

Julio
