VNC server behind firewall

I found several how-tos on web, but none of them suits my situation.
Basicaly I am novice to SSH tunneling and Putty, but I use VNC for
several years in local network.
This is my situation:
My computer (W2K) with local IP address 192.168.1.10.
Here will be VNC client.
My linux server (Debian) with local IP address 192.168.1.200 and
public address 212.55.x.x.
This server has SSH port accessible from Internet and local network.
Firewall, that has no open ports from Internet
My friend's computer (W2K) with public IP 144.60.x.x (obtained from
firewall's DHCP server). This IP cannot be pinged from Internet. But
my friend can ping my linux server.
Here will be VNC server
(I have created user account for my friend on my linux server. When I
started VNC server on my PC, friend created Putty session with SSH
tunnel (hostname: 212.55.x.x; tunnel: forwarded local port: source:
5900, destination: 192.168.1.10:5900), and he could connect to VNC
server on my PC directing his VNC client to localhost... But this is
not the problem. I need reverse situation)
Problem is that I cannot directly access VNC server on my friend's
computer due to firewall.
Can someone help, how to configure it?
My logic says that my friend has to create Putty session to my linux
server with some port forwarding specified (I cannot ping him, so he
has to be somehow reachable - via his ssh connection to my linux
server). But I have no idea what should I do on my computer to make it
Any hint welcome. Thanks a lot for reading my mail.
