By default, SGMI (port 2456) is only accessible via the interface that is
designated as the 'Inside' interface as configured via the front panel LED.
Additionally, instead of a traditional SSH connection, these firewalls use a
proprietary service the vendor calls Secure Remote Login that listens on
TCP/423 (not TCP/22).  This service relies on both a shared secret for the
SRL service as well as valid firewall admin credentials (so 1 user/pass
pair, plus a shared secret).  It requires a custom client that Symantec
provides (a modified TeraTerm Pro) called srlclient8.  This service is also
only accessible via the 'Inside' interface by default.

So if this is an external pen test of the firewall, and you can connect to
2456 (should get SSL challenge for cert signed by internal CA) or TCP/423,
these are findings in and of themselves, regardless of whether or not you
can actually authenticate and use these services to gain access to the
device.
