I have scanned my WAN IP with different tools and it is unclear if my router ports are actually closed.
Scans using nmap and iPhone apps show many open tcp ports (21,80,443,5222,5223,5228,5229,5230)
Scans using popular websites like Whatsmyip and GRC Shields-up report that all those ports are closed or stealth?
Is there a better way to confirm if ports are closed? I'm confused why I see mixed results.
I wonder if this may be to do with the ISP router I placed in bridged mode for ASUS to use as modem without double NAT. Could port scans be detecting the bridged modem-router?
Observation: When I port scan I don't see it in Skynet logs as being blocked or dropped. Is that normal?
