Configure Netopia dsl router to use static IP for VNC

Posted on 2011-04-19

I currently have a Netopia 3347 dsl router using PPP that has a dynamic IP from my ISP.
When I access my internal workstation(s) via VNC it works fine until
the public IP is reassigned. I have to be on site to get the new IP and edit my login IP:Port.
I requested a static IP from my ISP and recieved a range lets say

I am not using the dsl router as my LAN DHCP rather 2000 Server DHCP server.
How do I config router to use say as my public static IP while leaving
everything else as is?

My ISP currently has me turning off NAT on router and setting up exposed address range.
when I do this the LAN work stations cannot see the internet.  Nor can I ping any of the static
IP's from the outside.

Thanks /*

Use as service like dyndns so that you can use a hostname. Then you can install the dyndns client piece on a computer in your network that will keep track everytime your dynamic ip changes.

Why do they have you turning of NAT? You definitely need that to be on.

I believe they think I am going to use the DHCP on the router.
Because the next step is turn on DHCP and set up the range of
addresses.  I am looking into the dyndns as an option as we speak.
I will know if this will work shortly.

In my old set up I had a T1 line directly into my IPcop firewall. I could
designate my RED(outword NIC) with a static IP. Then set up internal
forward to my VNC server on the LAN.  Is it just not possible
using DSL and the modem/router.

If I use dyndns does the new IP have to propagate
each time it is updated through my isp's dhcp

This setup is VERY insecure...

I would suggest using something like Logmein - Hamachi (free), and VNC accross the software VPN.

This way you don't have to open any ports or reconfigure your router.

If you use the dyndns client piece on a computer on your network it will automatically update the new ip address to whatever dns you use. This way you don't have to worry about the account expiring because of lack of use or updates.

Thank you.  The dyndns client works well and will work in other apps where I need current ip.  I also tried the Logmein Pro2 remote and it is much more robust than the RealVNC I have been using and has a dynamic ip fuction as well.
