I would be most grateful if anyone can help me address my network
connectivity issues.
There are three routers that are connected on my home network, but only two
have computer connections.
1. Router 1 is a Netgear router/print server and is connected to the WAN
192.168.0.1. Linux Server is connected to this router as 192.168.0.9.
Router 1 is the firewall. I want to use VNC to connect to this Linux
Server.
2. Router 2 is a Linksys wireless router and is only used by the wireless
laptop. It has IP 192.168.0.10. DHCP is not active on this router, rather
DHCP is served by Router 1. The XP client that has connectivity problems
connects to the LAN via Router 2.
3. Router 3 is a Netgear/VOIP router for Vonage.
From the XP client laptop I am able to connect to the internet, print to the
printer attached to the Router 1 print server. I can mount network drives
from a Windows box attached to Router 1 but cannot open a VNC connection to
that machine. The Windows box on Router 1 can connect a VNC session to the
laptop on Router 2. The Windows box can also open an ssh-tunnelled VNC
session to the Linux Server either via LAN IP or by WAN IP.
The linux box on Router 1 uses ddclient and a free dns service to be
available from the internet. I can ssh to the box using either its LAN or
WAN address on the problem client laptop. I have set up an ssh tunnel to
tunnel VNC. The problem is VNC does not connect either locally or via the
internet hostname.
Any ideas about the VNC problem? The error message is "The connection closed
unexpectedly" and takes a while to pop up.
Both Windows machines use Windows XP with most recent updates, VNC 4.1.1.
I have read the related posts in the archives of this mailing list and have
looked for solutions elsewhere on the internet. There are no Events logged
when VNC fails.
I believe there is a problem with the configuration of the problem laptop
and I am eager to address it.
Thank you all kindly in advance.
