OK, that suggests a problem with the server and not the network.
Fix that before trying a connection from another machine.
What is documented for error 421? Might give you a hint.

Hi upon my observation that every ftp connection tried the vsftpd
process will spawn another process but the new process is the
ppid/mother of its original PID which is the pid in the
/var/run/vsftpd/vsftpd.pid. or the pid when we start the vsftpd using
init.d.
ps -ef | grep vsftp
root 6530 1 time ? /usr/sbin/vsftpd
root 6544 6530 time pts1 /usr/sbin/vsftpd
-----> failed ftp connection error msg 421 service available
root 6549 6530 time pts1 /usr/sbin/vsftpd
-----> another tried and failed ftp connection error msg 421
service available
and so on for every tried failed connection.
now another observation is when issue invoke-rc.d or inet.d/vsftpd stop
"root 6530 1 time ? /usr/sbin/vsftpd" will die but the
remaining child process still running and it will replace the mother PID
root 6544 1 time ? /usr/sbin/vsftpd
-----> failed ftp connection error msg 421 service available
root 6549 6530 time pts1 /usr/sbin/vsftpd
-----> another tried and failed ftp connection error msg 421
service available
and so on for every tried failed connection.
from then "invoke-rc.d or init.d/vsftpd stop" is useless it will not
work even if you create the "/var/run/vsftpd/vsftpd.pid" file with
6544($ mother vsftpd PID) on it..
Inorder to stop vsftpd you need to kill it all using pid
I tried to compile from source and replace the binary vsftpd but still
the problem happens..
Hope someone knows the issue..
