VNC, firewalls, and SBS2K
Posted on 2004-09-23
I am having a problem getting to VNC from outside of my internal network. I have a Zoom X4 ADSL Modem/Router (internal IP 192.168.0.253) which i have set up the virtual server to forward ports 5800 and 5900 to the corresponding ports on the VNC Server (192.168.0.253).
.253 is a SBS2K machine which is running VNC (the VNC client is on 0).
If i type in 192.168.0.253:5800 in a web browser on the internal network i can connect to it fine.
However if i type in 192.168.254:5800 in the browser, the page cannot be found.
I placed .253 in the DMZ and found the same thing happened (so the Tech support at Zoom can't help me)
I also set up Outlook Web Access SSL on port 443 which works fine internally, but again not externally.
However, email (ports 25 and 110) is going through the port forwarding no problem.
I uninstalled ISA server just in case... but it's still not working... I have no software firewalls on .253
Please...please... does anybody have any ideas?
