XDMCP connection failed with wirelessrouter


I have connection problem whem I use my wireless router between my pc and my modem.

I don't have problem to connect if my pc is directly connected on my modem.

I try to solve de problem with the help section of Xmanager with no result (configuring firewall section).

I try to solve the proble with linksys (my router company) technical support with no result.

at this point, what I can do if I must use my wireless router?


Program Ver. : Xmanager 3.0
Connection Method : XDMCP connection

Re: XDMCP connection failed with wirelessrouter

When you are behind a wireless router and connecting to a remote host outside of your network, you need to do port forwarding. Please look at the attached diagram:

To use Xmanager under NAT
Under NAT environment where PC is assigned to a private IP address, you have to use port forwarding to redirect incoming network traffic to user?s PC.

Here is an instruction:

Alternative method
If you cannot reconfigure your router or firewall, you can use SSH instead of XDMCP to launch individual X applications (including Gnome/KDE/CDE).

For instruction on how to launch X applications with SSH, please refer to the following link:
