greetings.
my state:
if I write the following in the browser: https://xxx.xxx.xxx.xxx:8006/
the system does not show me the administrative interface

when I make a tunnel reverse
ssh-L 1234:127.0.0.1:8006 root at xxx.xxx.xxx.xxx
I can connect to the browser http://127.0.0.1:1234/

Now apply the following iptables rules:

################################
#!/bin/sh
IPT=/sbin/iptables

$IPT -F;
$IPT -F INPUT;
$IPT -F OUTPUT;
$IPT -F FORWARD;
$IPT -X;

$IPT -A INPUT -i lo -j ACCEPT
$IPT -A OUTPUT -o lo -j ACCEPT

$IPT -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

$IPT -A INPUT -j REJECT
######################################


also secure server
* Locked root access via ssh
* Installing fail2ban
* Creating a user "userxyz" ssh access
* I added "userxyz" to "sudo"

I can not do the reverse tunnel ... : (

write: ssh-L 1234:127.0.0.1:8006 userxyz at xxx.xxx.xxx.xxx
answer: Received disconnect from xxx.xxx.xxx.xxx: 2: Too many
authentication failures for userxzy

I resolve this?
Thanks for your time!
