IPTables Ports 0 and 1 Closed instead of Stealth
Asus RT-N66U running on
Tomato Firmware 1.28.0000 MIPSR2-121 K26AC USB AIO-64k
Dears, I believe I found a bug related to firewall and/or iptables settings for the shibby tomato firmwares.
I am using the default settings for Firewall:
NAT loopback: All
NAT target: Masquerade
UPnP Enabled
When I run a GRC.com ShieldsUp test against my router, ports 0 and 1 shows as Closed instead of Stealth, which I believe can increase the risk of an attacker to detect a "valid" computer running at my ip-address.
I've tried several different rules on the firewall script gui trying to drop packages "incoming" to these two ports without success. Anyone with the same issue related?
Thanks in advance.
