Tunneling through unfriendly firewalls

I just posted a description of some tunneling I'm doing in 
http://www.nabble.com/forum/ViewPost.jtp?post=7902748&framed=y this thread .
I'm basically getting port 80 traffic through an encrypted tunnel so I can
use a web server that's behind a firewall. The problem is, all port 80
traffic on the web server side of the firewall is not encrypted. I tried
being clever:

ssh -L 2345:firewall:3456 bforbes@firewall
ssh -L 3456:webserver:80 bforbes@webserver

But I think the firewall has some restrictions on users creating listening
ports, because I get this:

      channel 3: open failed: connect failed: Connection refused

whenever I try to forward packets through my port 2345.

Is there another way to achieve this? Surely if I have an encrypted tunnel
all the way through to the webserver, there is someway to send port 80
traffic through it, regardless of the firewall's restrictions?
