I just made some progress. (not much, but it is a start)

I run HTTPort like this:

Local Port: 6346
Remote Host: gnutellahosts.com
Remote Port: 6346

And SocksCap like this:

Socks Server(v4): 127.0.0.1 1080
To run BearShare "sockisfied"

When i run GNetWiz "sockisfied" with this configuration it says BearShare should work fine.

Now BearShare says this:
gnutellahosts.com: Trying -> Connected 10s 9s ... 0s Service -> Closed
router.limewire.com: Times out (which is logic, becouse it isnt in HTTPort)

HTTPort says stuff like this:

------------------------------------
SOCKS4[24.131.163.246:6346]: 0103 Invalid connection id
------------------------------------
SOCKS4[172.144.230.79:6346]: 0103 Invalid connection id
------------------------------------
SOCKS4[206.132.188.135:6346]: 0202 Connection state closed
------------------------------------

I cannot change any setting in the firewall, so thats why i have to tunnel thru the company's proxy (80)

Maybe someone can help me on this, thx
