Port Forwarding Issues

I have setup VNC clients/servers on my network computers so that I may
access them remotely. Internally they work via the respected
192.168.x.x:port. Now i would like to access them via the internet
through myip:port.
Reading on this subject I have to setup Port Forwarding through my
router to send the information to desired machine, so i setup the Port
Forwards for each specific machine that I wish to connect to and
configured their VNC servers for the desired ports.
For some reason I cannot connect to any of the machines in this
fashion when i use the main IP address of the router:port combo. The
only way I have been able to connect is if I assign one machine
through my router to recieve the Static IP address and then i can only
connect to that computer, no others.

I am unclear on what other issues it may be, could it be that my
router is set for a Private LAN and not a Public LAN?? Anytime i set
to Public it crashes the router and i dont connect to my ISP and have
to re-configure the router! At this point I have the Firewall
completely disabled on the router so that it will let any and all
traffic inside so I dont think thats an Issue. I have been working on
this issue for several days and still have yet to make any ground.
Does anyone have any advice?

I am using a Westell 327w Versalink Router/Modem (Version
B90-327W15-06)

Thanks for reading, any help on this subject would be appreciated.

Set up a separate port forward for each machine to a different port

example externalip:9800 -> internalip1:9800
example externalip:9801 -> internalip2:9800
example externalip:9803 -> internalip3:9800


There are security issues in using VNC so you may want to be sure you
have strong passwords and limit the range of ips you allow to connect
inbound. You might also consider tunneling the traffic via SSL or using
a VPN.
