I have a Comcast ISP connection and a modem with 4 ports. I have three routers, each connected to one of the ports on the Comcast modem, each assigned a separate static public IP on same subnet on the WAN interface. The LAN side of my routers are assigned the IP address 192.168.0.1. Router A is the main router and my servers are connected to it. Routers B and C are routers that go to lab computers.
My question is this - I cannot access some public facing services such as FTP or RDP on the servers connected to one of my routers from computers connected Lab routers B and C but can access those from sites outside of my network. Does anyone know why?
