I have a Westell 7500 modem/router (two actually) from Frontier. It is setup in bridge mode, passing through to a Cisco RV042 load-balancing router. The Cisco is setup to update DynDns for my domain, and it appears to be working fine. The Cisco load balancer passes through to a Buffalo Air Station router running DD-WRT v24SP2. My PC workstation running the website is connected to the Buffalo router.
When I connect to the PC Workstation from another computer below the Buffalo Router, I am able to see the website fine. When I check my connection using the OpenPortTool, it always times out.
I have tried with all firewalls disabled. I have set the Cisco to forward all ports to the Buffalo Router, and I have set the Buffalo Router to forward all ports to the PC Workstation.
Does anyone have ideas on what could be wrong?
Here is a diagram of my network setup: Network Diagram
Thank you for any help.
