Yes two router but :


1st level router is a Virgin Media Hub 5 that I have now turned off the
Firewall (but do not think it applies) then set it to be a modem only.
This is connected via Lan cables to a Asus RT-AX82U Router that lins to all 
the
household system via both Lan cable and some Wi-Fi systems but mostly the like
of phones, Hive hub etc.

The main system including that of the Linux based BBS system is wired direct
via 1 Gb Lan cable.   This router has been set to transfer incoming via
advanced WAN settings-> Virtual SErver / Port forwarding to :

FTP Server     20,21      21     192.168.1.3 TCP
HTTP Server    80         80     192.168.1.3 TCP
Mailer         24554      24554  192.168.1.3 BOTH
torrent        6881:6889         192.168.1.3 BOTH
TELNET Server  23         23     192.168.1.3 BOTH
ssh            22         22     192.168.1.3 BOTH

The settings for Telnet and SSH was originally set for TCP but I changed it to
BOTH when first seeing the problem.

Now FTP, HTTP, Mailer all work (Torrent) is not used on .3 anyway)

The new connecting link set up are the last two and nothing happens other than
a refused message but have no idea what is causing it such as before the modem
or the router there are no messages in the log files for mbse mailer etc
regarding such a connection.

In file xinetd.conf has a includedir entry for  /etc/xinetd.d  which has the
services for:
binkp
fido
tfido

and
telne :

# Telnet to the bbs using mblogin, disabled by default.
#
service telnet
{
        disable         = no
        protocol        = tcp
        instances       = 10
        flags           = REUSE
        log_on_failure += USERID
        socket_type     = stream
        user            = root
        server          = /usr/sbin/telnetd
        server_args     = -L /home/mbse/bin/mblogin
        wait            = no
}

It is not disabled

In /var/log/security.log there is no instances regarding telnet.

I am going to restart the system as mbse is refusing to shut down ie mbtask is
still running so see what that does not holding my breath.
