Linksys PTZ IP Camera Not Accessiable Over The Internet

   We have a client that we just upgraded from a bunch of workgroup PC's to a SBS on a domain. DSL modem. After the upgrade, the 4 PTZ IP WVC200 cameras that used to work using DDNS Sololink over the web no longer work. They are able to be viewed inside from a browser, but not from outside the network (on the internet). Even though all the ports are setup the way they used to be. They all have internal static IP's, DNS is setup correct. But no luck.
    Now the shop has a static IP, which it didn't use to, so when I try to connect over the static, say - 216.216.216.216:1024, I get a "page cannot be displayed" error. I get the same exact error when I setup the Sololink piece that used to work. However, once I set the Sololink up on the camera's pages, it takes the configs and says congrats, but when I close the browser and get back into it, it is all blank again. Has anyone seen anything like this?
    I have tried two different modems and just today took one to my house and set it up there and I get the same results. Anyone that can help would be greatly appreciated!!!
    I tried a firmware upgrade on 1 and it didn't make a difference.

Thanks in advance!
