Hi,

I don't know if it is best to post this question to windows.networking
or linux.networking. So I decied to go for both.

Here is my problem:

I have a Windows Xp workstation at home. I am using ADSL via ADSL-modem
Zyxel Prestige 660 Series. The modem/router supports NAT.
I recieved a dynamic address from www.dyndns.org
The ip,81.224.94.138, is my adsl-modem/router. And name is
freemindworkz.mine.nu I am runnning Real VNC on Xp machine port 5900.
I want to connect to my computer at home from my solaris bax at the
office. Is it possible? How?

I am really stuck so all information is esential.

Status now:

Now my thinking is that I need to convert the domain-name to a specific
service/computer on my LAN ( well right now I only have one computer ....).

I discovered NAT. It seem like it is possible to convert one ip to many
ip:s using ports.

But since I only have one computer on the LAN I don't have to setup
specific ports. All requests will be directed to the same computer.

I tried ping my machine 'ping wwww.freemindworkz.mine.nu:5900' at home
without any luck.
Result:
ping: unknown host wwww.freemindworkz.mine.nu:5900

Assuming that's not a typo in the post of course,
wwww.freemindworkz.mine.nu doesn't work because you misspelled the
address (wwww -> www). I'm guessing you really did it wrong on the
box because it's spelled the same in both places.

this looks like a DNS problem! Try pinging your machine by its IP number
81.224.94.138:5900 if that works you know that the problem is with
DNS itself. But to tell you the truth it looks like you have a
networking problem beyond DNS itself

I don't see in your description where you port forwarded port 5900 to your
internal computer IP address.

Just an addition.
Did you enable wildcards when you register DNS?
Try something like nslookup to troubleshoot DNS and dont forget to open the
port 5900

You need a VNC client at the Solaris box. Have a look at

The name resolution does work - I tested it.

ping cannot be used with an URL: there is no port number, try:

ping wwww.freemindworkz.mine.nu

instead.

If you get no answer, it's fairly possible that your employer's
firewall eats the pings.

To test the visibility of the VNC port try:

telnet wwww.freemindworkz.mine.nu 5900

It does not produce anything sensible on the terminal, the VNC
protocol is not printable, but you'll see if it's getting anywhere.

If the firewall does not pass the VNC connection, you have to
carefully approach the EDP departement with the request of opening
access to outside TCP/5900 port. There are tools for piercing the
firewall, but it's not too healthy to apply them in a telecom
company - the risk that somebody understands the set-up it too
large.
