well except for the fact that I was forced to set our router to use a dynamic IP instead of static like it is supposed to be.
Don't confuse your WAN IP with your LAN IP. The WAN IP is the one exposed to the Internet and the LAN IP is for comminicating within your LAN only. They are completely different. If your ISP assigns you a static IP (generally costs more) then you would insert that specific static IP for your WAN connection. If in fact your ISP doesn't assign a static IP (quite common), then your WAN connection must be set up as "automatic configuration-DHCP)
Your LAN IP would be set up to be static, starting with 192.xxx.xxx.xxx. The LAN IP is of course static, but the WAN IP could be either, depending on your arrangements with your ISP
You mention that the (WAN) IP is supposed to be static - confirm with your IP if this is in fact so.
