Problems setting up a VNC connection from uni to home (SMC
Fri Sep 26 13:09:00 2003
Hi guys I've trawled through some of the recent months posts looking for
help, and I thought I'd covered most of the tips but I still don't seem
to be able to connect to my home desktop which sits behind a SMC
I'll quickly give a brief description of the setup.
I'm on the Telewest Blueyonder broadband at home (UK), which as I
understand does change its IP addresses every 24 hours.
The SMC barricade serves 2 desktops and 1 laptop (when its there). My
desktop which I'm trying to connect to has the internal LAN IP address
Using the SMC setup menu through IE6, I have done the port forwarding
through SMC's Virtual Server section, however from the posts I've seen
here mine doesn't make any mention of a service port, instead there are
about 5 columns, the first being the IP address of the machine behind
the Lan whose ports I want to forward (my desktop), then the private
port I want to forward, the public port and whether its is a TCP or UDP
connection and a box to tick if I want the set up to be enabled.
So I have 2 entries: Private IP: 192.168.2.22 for both, Private port
5900 & 5800, Public Port 5900 & 5800, TCP checked on both, and both
enabled. I thought maybe I messed this bit up but I called SMC and the
technical support guy verified that it was correct.
Then I thought I may have got the wan IP wrong so called up Telewest to
check if their IP address they had for my house was correct which it was
and it was so I'm stumped now.
When connecting from Uni I have used just the wan IP address (x.x.x.x)
the wan IP with the port I want to connect to (tried both x.x.x.x:5800
Every time I get the Connection time out error.
I've got it to successfully work within the LAN, but can't seem to get
it to work from uni so I'm not sure if it is a problem at UNI or a
router problem. I was wondering whether I can connect to the desktop
from another computer on the LAN to the desktop by going out and back in
(e.g. by using the wan IP) but I'm not sure how to do it cos I'm not
sure what additional ports to forward
Oh yeah- the laptop I'm trying to connect to the desktop runs XP pro,
and the desktop has XP home edition (Service pack 1 on both machines as
well), and both have Zone Alarm Pro 3.7.159 running, but zone alarm on
both allows VNC to connect I assume seeing as I can connect on the LAN.
If anyone could please help me I'd very very grateful,
Thanks very much you guys
