Can't print with IPPS.

I can't print when Mac and Printer are connected through XG Firewall's bridge.
Mac - XG br0 - Printer

I can print by disabling SSL/TLS engine. Or I can print by disabling IPv6.

IPPS (Internet Printing Protocol over TLS) is used for printing.
When IPv6 is enabled, IPPS uses link-local addresses (fe80::/64).

The firewall log is output as Allow.
If I can print, application is identified as 'SSL Traffic over Non-SSL Ports'.
If I can't print, application is blank and the SSL/TLS inspection and Web filter logs will not be output.

Does SSL/TLS engine have problems handling link-local addresses?

I'm using SFOS 19.5.1 MR-1-Build278.

  • I built a test web server and tested this issue.

    With HTTPS, it could not be accessed with the link local address.
    Same with using Web Proxy.

    With HTTP, it was also able to access the link local address.

    XG doesn't seem to be able to handle the combination of TLS and link local addresses.
