I'm assuming we're using the Zhone as the modem and the router, leaving out the Linksys router completely.
http://www.zhone.com/support/manuals/docs/63/6388-A2-GB20-00.pdfIf I'm reading the manual correctly, setup a LAN client first (pg. 3-29), under Advanced > LAN Client.
Provide the Wii's MAC address, name the connection, and designate an IP address that fits within the IP range you provide under Setup > LAN Configuration. (pg. 3-19)
The router's IP is 192.168.1.1, then the Start IP is a .2, and the end IP could be a .11, for a total of 10 computers/devices maximum (whatever the need of your network). It's better if the Wii was assigned the very last one, the .11 in our example.
After that, you can assign the DMZ to the Static IP we want under Advanced > Port Forwarding. (pg. 3-27)
Then, go into the Wii connection setup and fill in the info according to
http://www.nintendo.com/consumer/systems/wii/en_na/getOnline/manual.jspbut with these exceptions:
static IP: use the one you decided
DNS servers: use the router's local IP, 192.168.1.1
MTU value: use the value already in your Zhone's PPPoE configuration (pg. 3-8); my ISP didn't tell me what to use, so I chose 1500 for my router and Wii
