|Ok, what is your configuration on all the aforementioned routers?|
I don't need, or want, the exact external IP(s). The first two octets followed by x's will do fine (ex: 69.54.xxx.xxx) for statically assigned external IP's. If they're DHCP, just say so, the actual IP isn't that important.
If you're using private IP addressing internally, the exact TCP/IP settings on all internal interfaces will be very helpful in assessing your situation.
Are you using VLAN's? If so, how is your switch configured?
Exactly how many external connections do you have? What type? What does each connect to?
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
