post your iptables rules:

~#] iptables -L --line-numbers


well steve, you have it configured, but i am confused about the first few lines, specifically the first:

1    QUEUE      all  --  anywhere             anywhere
2 ACCEPT all -- anywhere anywhere (NB - this should refer to loopback) 3 ACCEPT all -- anywhere anywhere (NB - and this one, the internal NIC)

if your input policy is set to DROP everything, but your first rule is "QUEUE everything from anywhere to anywhere". according to the iptables man page:

"QUEUE means to pass the packet to userspace (if supported by the kernel)."

do you have some userspace app that will handle all these packets? i may be way off, but if you don't then wouldn't this be the equivalent of allowing everything from anywhere to anywhere?
