SSH tunnel - administratively prohibited?

Hello,

I am trying to use a SSH tunnel to my university as an alternative to a VPN. The university explicitely shows this using a SOCKS proxy, which forks fine, but changing the setting in Firefox is relatively uncomfortabely.

I only need to access one specific host in the university network, which is on a different computer than the SSH server. So basically what I wanted to do is to :

$ ssh -L 62000:remote-server-in-university-network:8088 me@university.

But this does not work. When I try to open localhost:62000 on my network, I always get "channel 3: open failed: administratively prohibited: open failed".

The weird thing is that this issue also appears when I try to use a ssh config file using the SOCKS approach, (just tunnel to localhost on the SSH server); but otherwise the exact approach from above works when I use JuiceSSH on Android. So I guess the problem is on my client side PC.

Does anybody have any idea about that?
Thanks!

Edit: Weird, now it works... But I don't really understand why.

How about an FF plugin for proxy settings?
