Two possible ways I can think of, both are going to take some time & experimentation:
1. Will need two proxy servers running on the same box & 3 NIC?s. One binding to 80, the other 8080 or something else. An added thing would be also have a DHCP assigning hardware router, or run a DHCP Server such as MS between the router and your network for ease of adding new nodes. Just don't have the Cable1 and Cable2 on the same initial ports and have the Proxy servers combine the outputs in to the DHCPServer.
Network path: CableModem1 to NIC1 on Proxy1 ? CableModem2 to NIC2 on Proxy2 (Proxy1&2 on same box) NIC3 (On same box) to DHCP server NIC1 - DHCP server NIC2 to your LAN (HUB) (Can your game server with the 2 NIC?s act as the DHCP Server? Follow this?
2. Use FreeBSD (Or other Linux type OS) set up as a Load balancing router:
Network path: CableModem1 to NIC1 on Linux box - CableModem2 to NIC2 on Linux box, NIC3 on Linux box to your LAN (HUB) or to your GameServer NIC1 & GameServer NIC2 to your LAN (HUB).
So, how good are with TCP/IP setup? You will need quite a bit of know-how either way you go. I do not personally know of anyone with the Load balancing router setup. But have heard that would be possible. That?s the bestI can come up with. Let me know what you think & if/how you do it. Good luck ;-)
Like I said in the 1st Post (I still think this is your best bet & found it for under $83.00 with S&H). What are yours/your client?s time worth? Think about it, the above setup(s) could take DAY?s!
