ASA clientless SSL VPN (WebVPN) and AJAX pages

Unanswered Question
Mar 12th, 2009

Can anyone tell me if ASA (5505 on 8.04) supports using Ajax web applications through the WebVPN portal?

Specifics : I am trying to use the management pages of a Synology NAS running Disk Station 2 software. This management page uses Ajax.

It looks like the ASA cannot handle this.

I have this problem too.

You may try configuring the thin-client SSL VPN (port forwarding). A remote client must download a small, Java-based applet for secure access of TCP applications that use static port numbers. UDP is not supported. Examples include access to POP3, SMTP, IMAP, SSH, and Telnet. The user needs local administrative privileges because changes are made to files on the local machine. This method of SSL VPN does not work with applications that use dynamic port assignments, for example, several FTP applications.

I has this working with an ASA5505 using clienless SSL and my Synology CS407 using DSM 2.3-1157 but Synology have now upgraded the DSM software to DSM v3.0 which seems to be broken when using an SSL clientless connection through the ASA.

is these anything I can do to stop the ASA SSL screwing up AJAX and allow me to actually see the default logon panel of the CS407?
