Similar to the other poster, we have had Cox Internet now in testing against our current bonded T1's. The Cable beats the T1's even considering the asynchronous nature of it. The problem is the stability of the assigned static IP's.
The first set never worked, the 2nd set only half way worked. The third set finally provided a clue (at least to me although company techs at the time denied it was the problem) that the modem itself can only pass through two static IP's.
I had arrived at this conclusion asince that is exactly what was happening.
The 5 port switch connected to the cable modem to provide a line for each IP to feed routers used by VPN's or other devices needing a static IP. I could always get any two to work. But the third one always had to be set to dynamic or it would not connect. And on dynamic it would go far afield for the IP not even close to the range we had been assigned.
Today, I had a COX tech tell me this was absolutely correct although up till now, no one else would say so.
However, he said it is still possible to use all 5 static IP's by running the output of the cable modem into a router instead if a switch. The run the output of the router to the switch to split the signal and from there on to various devices needing the static IP's.
While I can envision such a setup, I have a problem with understanding the logic for it or how to program the settings to allow all ports for each IP to pass. What part does the router in-between the Cable modem and the next router do in this layout?
All 5 IP's don't go to other routers, some go to standalone devices needing their own public IP. One is a videoconference system which requires a static public IP. One is a router that provides the Office Intranet, one is providing signal to a Web-Site Server. One to our Mail-Server.
The 5th goes to another Web-Site Server. The website servers being the host for the websites on them need a static publicly accessible IP.
I am willing to give this a try but cannot get anyone to explain what settings I should use in this "bridge" router? Or whatever purpose it serves, If I knew, maybe I could figure a proper configuration.
