vnc using dynamic IP

ssherm32 · Post by **ssherm32** » 2006-01-31 20:56

I have a small network behind a Linksys router. The net is conected to the internet via DSL and has a registered domain name using a dynamic IP. It is possible to use VNC between two machines within the lan, but I am unable to access the host via the internet using the domain name (dynamic IP). The router is set up to forward ports 5800 and 5900.

This arrangement has worked satisfactorily using Netop, so I am unclear why I cannot get it to work with VPN. Any help would be appreciated.

For UltraVNC SC you don't need any incoming ports opened or forwarded in your firewall - that's the reason you are using the SC version instead of the normal UltraVNC. You just need to make sure you don't block the outgoing port you configured in the [Host] section of your helpdesk.txt when assembling your custom SC file.

Code: Select all

[HOST]
-connect 123.456.789.123:80 -noregistry

You see above it is port 80 which is normally never blocked.

[HOST]
-connect 123.456.789.123::80 -noregistry

--> you need to double colons :: !!! <---

explanation applicable for any vnc flavor:

:display (0 - 99 == accept only 5800 to 5899(for http) and 5900 to 5999(RFB protocol)
example: port 5901 == display N° 1
::port (any port outside of standard port need double colons)
examples:
::80 (SingleClick connecting as non standard port)

Hmm, I'm working with one double colon and I don't have any problems. Is that a normal behavior? Maybe SC detects the missing second double colon and corrects it itself ... but good to know to set two in the future.
