Hi, just port scanned my 2800 from off-site using nmap and found several ports flagged as closed and not filtered as I expected. Using Gibson Research site Shields Up indicates that they're all stealth (filtered) which I have always relied on for testing ... won't be doing that anymore. My first firewall rule is block all incoming packets "if no further match" and there's definitely no later rules opening these ports. Firmware is latest UK 2.8.2. Any ideas if it's possible to properly stealth a 2800?
