Accessing ssh proxy from another host

view story

http://unix.stackexchange.com – I'm used to setup a ssh proxy in the localhost like this: ssh -fND 9999 server I have been using it for years for daily browsing. Now I want to use the same proxy in a Windows guest in the same desktop host. The host (Fedora) is at and the guest is at But when I set the proxy as a socks5 proxy in Firefox at the Windows guest pointing it to it times out. I did open the 9999 port at the firewall. The same thing happens when setting the proxy up in another host (Centos 6) and trying to access it from my Fedora desktop. So what am I missing? (HowTos)
