The ACME client is unbound from wan1, which removes the HTTP-01
challenge listener that had been holding port 80 open irrespective of
allowaccess. An external sweep of fifty-five ports against the WAN
address now finds nothing open at all, while the internal interface
still serves the GUI and SSH and retains its certificate, which
remains valid until late October and simply stops renewing.
The previous note's claim that four virtual IPs were unrestricted
all-port static NATs is withdrawn. A FortiOS virtual IP can be scoped
either by an explicit forwarded port or by a service binding on the
object, and the earlier parse inspected only the former. All four use
the latter, and the custom services behind them are narrow. None of
the fourteen is unrestricted.
Ground truth from outside is recorded in place of further config
reading, listing what each public address actually exposes. Three
configured mappings answer nothing at all and are noted as tidy-up
candidates for the migration rather than as exposure.
