ftp port 21 and 20 not showing
I can't get ftp working on one of my servers. It's Ubuntu 14.04 that is the trouble. The same iptable instructions works on my Ubuntu 16.04 server.
Even when I set INPUT, OUTPUT, and FORWARD to ACCEPT at the top I can't see port 20 or 21. Port 22 is fine. vsftpd is running.
Here is my current iptables rules where I've changed everything to accept.
*filter
Allow all outgoing, but drop incoming and forwarding packets by default
:INPUT ACCEPT
:FORWARD ACCEPT
:OUTPUT ACCEPT
Custom per-protocol chains
:UDP - [0:0]
:TCP - [0:0]
:ICMP - [0:0]
Default policy
-P INPUT ACCEPT
-P OUTPUT ACCEPT
if a matched ipset then drop put this first
-A INPUT -m set --match-set ScottHillBlocks src -j DROP
-A INPUT -m set --match-set ScottHillAddr src -j DROP
Acceptable TCP traffic
-A INPUT -p tcp --dport 22 -j ACCEPT
-A OUTPUT -p tcp --sport 22 -m conntrack --ctstate ESTABLISHED -j ACCEPT
FTP ports 20 and 21 active
-A INPUT -p tcp -m tcp --dport 21 -m conntrack --ctstate NEW,ESTABLISHED,NEW -j ACCEPT
-A OUTPUT -p tcp -m tcp --dport 21 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT
-A INPUT -p tcp -m tcp --dport 20 -m conntrack --ctstate NEW,ESTABLISHED,RELATED -j ACCEPT
-A OUTPUT -p tcp -m tcp --dport 20 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT
