Port forwarding through firewalls

Oct 06, 2005 0 Replies

Here is my issue I usually run a support application which is a customized version of UltraVNC server. It launches from a client machine and attempts to connect on port 5555 to my offices WAN IP. The firewall redirects the port to my computer and I can see my clients computer as soon as the connection is made to my VNC viewer operating on listening mode on port 5555.


It works great but now I am traveling and I a hotel and want to have the same functionality. There fore I need to forward the data coming in on port 5555 on my office machine to my laptop which is BEHIND a hotel firewall.


My solution to use Zebedee in reverse tunnel mode. So I run a client on my computer with the following configuration file.


debug true



verbosity 2 # Basic messages only



message "client"



detached false



Server false



Listenmode true



Tunnel 8000:*:5555


I then connect to the client by running the server on my computer


debug true



verbosity 2 # Basic messages only



message "Server"



server true # It's a server



detached false # Detach from terminal



serverport 8000



clienthost SUPPORT


I get a connection established on the client on my work machine. So I have established the connection to the client through the hotel firewall and our work firewall. However when I try and run the VNC server at port 5555 on my office machines nothing happens on my laptop.


I have tried several variations of ports and commands. I think I fundamentally misunderstand something. Remember all I am trying to do is redirect traffic arriving at port 5555 to my laptop on the road which is also behind a firewall.


Can someone help me out with my configuration?


Thanks
