So, in other words you have changed your ISP to Karib Cable. Is that correct? You may have to replace the asdl modem with a router. I don't know if they are compatible. If you want to try it, run the WAN port of the asdl modem to the cable modem. It may see the 206.126.120.xx address & continue to do the NAT as it did before.

How do you know when a politician is lying? His mouth is moving.

I got rid of the adcl modem, with the adsl modem I were able to access it, give it a static ip address, point it to my dns and disable dhcp 'cos my server is already running dhcp and is also a dns. However with the new modem from Karib Cable they gave me they own ip address but it dont fall with in the scope of my ip and my network, when I connect the cable modem directly to a pc its works perfect. I'm so lost, i hope explaind myself a little more.

You need a router. A router takes your one isp ip and converts it to many lan ips. You just configure the lan side to be in the present lan ip plan.

Sorry I cant get a router at this time, I', trying to set up NAT between the 2 nic in gon on my windows server 2003. I giving me hell, a proxy server is even harder. Ok, heres what I got the internal nic configured in my LAN, all pcs can connect, share files etc. My public nic is configured with the ips my isp gave me, I got internet only on the server but somehow the NAT is not bridging the gap for my LAN to get internet, I tried everything (I think), what am I missing.
