Hi!
I noticed that after I have set up my ip(+6)tables up to filter unwanted incoming traffic all "inbound" and "directory" connections in nyx disappeared, only lot of "outbound" connections are there.
I am running exit relay (IPv4+IPv6) on ORPort 443 and DIRPort 80.
Is there someone willing to check my iptable rules? I am starting to lose it...
My iptables: -P INPUT DROP
-P FORWARD DROP
-P OUTPUT DROP
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m conntrack --ctstate NEW,ESTABLISHED -m tcp --dport 22 -j ACCEPT # SSH running there
-A INPUT -p tcp -m tcp --dport 443 -j ACCEPT # allow incoming comm to ORPort
-A INPUT -p tcp -m tcp --dport 80 -j ACCEPT # allow incoming comm to DIRPort
-A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT # allow all already established incoming connections
-A OUTPUT -o lo -j ACCEPT # allow all outgoing connections
-A OUTPUT -o eth0 -j ACCEPT
My ip6tables:
-P INPUT DROP

Thank you all for any replies!
Have a nice day.
