SSH port forwarding and Webmin

[Eddie]

I have webmin installed on a brand new installation of FreeBSD 5.2.1. I 
tunnel port 10000 to my localhost and connect to wemin like this:

http://127.0.0.1:10000

I always connect to webmin this way, with all *nix machines I admin. 
This does not seem to work with FreeBSD 5.2.1. It does work out of the 
box for other versions (4.7 and 4.8 at least) of FreeBSD though. Is 
there some rule somewhere preventing port forwarding in 5.2? Here's my 
netstat output:

bsd3c# netstat -nat
Active Internet connections (including servers)

udp6       0      0  *.514                  *.*  

webmin is running and listening on port 10000 as it's supposed to, and I 
can connect to webmin on the localhost with links. The sshd config file 
gives no indication that tunneling is disabled, and it has not been 
modified in any way.

I would be glad to hear what anyone's thoughts are on this.
