My Work LAN have a firewall with 2 NIC
(RED)xx.yy.xx.6 and (GREEN)192.168.0.254

I installed ssh server on firewall: OK
I installed ssh server and vnc server on MyServer (NIC IP 192.168.0.5)

With my home pc i try ssh connection and it's all right.
Also vnc server it's all right. (I use DNAT from port wwww on my
firewall to 5901 on myserver) (display=1)

Now i want to use a secure tunnel.

I try with:

ssh -f -L 25902:192.168.0.2:5901 ivan@xx.yy.xx.6 sleep 10; vncviewer
127.0.0.1:25902:1

but it doesn't work.

me

TIA
IK

I'm gonna be nice and assume english is a second language and forgive
the "command" form of " me" in lieu of the more polite "Can anyone
please me?"

A few things I'm thinking:
your port forwarding in your ssh command goes to 192.168.0.2
but you told us your vnc server is on .5

your ssh command may only hold a connection for 10 seconds.

dunno if -f is causing things to break.

You may want instead:

ssh -L 25902:192.168.0.5:5901 ivan@xx.yy.xx.6 "perl -e 'while(getppid > 1){sleep 15}'"
