I am facing a challenge i.e. we have some users inside the LAN who needs to access a SFTP server which is outside the LAN and we need to make this possible by using our ISA 2004 server which is acting as a proxy and firewall client for our LAN users. <br />
<br />
I created a rule in ISA 2004 that traffic coming port 22 from user computer going to SFTP server outside should be allow, but on the ISA 2004 monitoring I only able to see ISA initiate a connection and then closes that connection; and user is unable to connect to this SFTP server.<br />
<br />
Probably, I am doing something wrong or it is not suppose to be done this way, any help would be appreciated from all the experts. &nbsp; &nbsp;

SFTP via ISA 2004

Microsoft Forefront, formerly known as Internet Security and Acceleration Server (ISA Server), is a network router, firewall, antivirus program, VPN server and web cache that runs on Windows servers. It includes identity management and protection systems, and discontinued systems for threat management and network protection, along with protection for Sharepoint and Exchange. The scope of discussions includes forward and reverse proxy, application and service publishing, virtual private networks (VPNs), outbound access rules, SSL certificates and network routing within either a single node or an highly-available array pairing.
