I have a Zoom X5 ADSL modem/router and a DI-524 router.
I needed to turn the Zoom X5 into a modem only and use the DI-524 for router functions (DHCP Server and NAT).
What drove this configuration is that when I signed onto XBOX Live with only the Zoom X5, log-in would take forever and then every once and a while it would lose connection XBOX Live.
I then tried doing port forwarding by manually entering NAT rules that satisfied the port forwarding. This only caused STRICT NAT (symmetric NAT) settings according to the XBOX Live Network Test.
I then configured the Zoom X5 to full bridging function (turned off DHCP server, Nat Functions, and LAN settings). Connected the DI-524 to the Zoom X5.
Zoom X5 (LAN1 Port) ------> DI-524 (WAN Port) Computer (NIC) -------> DI-524 (LAN1)
Shut off DI-524. Rebooted Zoom X5. After reboot of Zoom X5, I turned on DI-524.
After WAN Interface indicator was constantly on, tried internet with IE 7. No connection.
Tried ping well known ip address on internet. No response.
Logged into web interface of DI-524. Looked at status of WAN. It showed "DHCP Client Not Connected".
Reconfigured hardware:
Zoom X5 (LAN1 Port) ----> Computer (NIC)
Repaired Local Area Connection Status in Windows XP.
No Problems with getting public IP address. Good internet connection.
Reconfigured hardware:
Zoom X5 (LAN1 Port) ------> DI-524 (WAN Port) Computer (NIC) -------> DI-524 (LAN1)
Logged into web interface of DI-524. Changed WAN configuration with the MAC address of the computer's NIC card. Did a reboot on the DI-524. All is good.
No why did the ISP (Verizon) not accept the DI=524's MAC address, but accepted the computer's NIC card MAC Address?
As of now the present configuration has been up for two days.
