Japanese FLET's ADSL/IP-Denwa & AirPort

fulmer

Does any one know how to setup the FLET's ADSL Modem-NV (Japanese) and an AirPort Extreme together?



Here's my setup:

1) I've got the ADSL modem (Modem-NV 24Mbs) setup to automatically connect to my ADSL and IP-Phone using the setup page (http://web.setup/ or http://192.168.1.1)



2) I've set my G5 (192.168.1.3) and my Linux box (192.168.1.201) to manual IP address settings (both using ethernet not wireless)

(I just sold my old G3 iBook and plan to get a new 12"PB once the new ones are released)



3) I've set the AirPort base station to forward ports to specific IP addresses (192.168.1.3 & 192.168.1.201)



4) I've set the AirPort base station to use Ethernet/DHCP for the internet tab and DHCP for the network tab



5) I turned off DHCP in the ADSL modem settings (I think )



Here's the problem:

1) If both the ADSL modem and the AirPort base station are connected (telephone line -> sliter -> ADSL modem -> airport base station -> network) I can't access the internet or the ADSL modem's setup page. The AirPort base station wont allow me to connect for some reason.



2) If only the ADSL modem is connected (telephone line -> sliter -> ADSL modem -> network) the AirPort base station is not going to be able to forward ports (duh)



3) If the ADSL modem isn't hooked up (telephone line -> sliter -> airport base station-> network) I have no internet (duh)

It doesn't sound right that you have assigned fixed IP addresses to your computers but Airport is setup as a DHCP server.



Just for fun, set your computers to DHCP and see if they connect.



I used a similar situation when I lived in Japan. We had the FLETS ADSL modem connected to an Asante router which served IP addresses to three Macs. In this configuration I was able to forward specific ports to specific computers.

I modified my original message to make it a little more clear.

I need to keep my G5 and Linux boxes set for specific IP addresses since I'm using the Linux box for a web/mail server and the G5 is setup for VNC. I did try setting them to DHCP, but nothing changed. I think there is a setting in the modem that needs to be modified. I've been messing around with it for almost 1 week. I can usually figure these things out in less than an hour!



I've also tried messing around with the ADSL modems settings to see if I could get it to forward ports to specific IP addresses, but with no luck. Everytime I think I've got it, it doesn't work

I reread your message and something finally sunk in. You mention that you set the modem to connect automatically. Usually the modem can't do that, either the router or your computer makes the connection. I now recall trying to use a router at my in-laws home in Ichikawa. They have Yahoo ADSL. That router could connect automatically and the computer then would connect to the modem using DHCP.



It wouldn't work if we switched computers. We finally learned from the help line that if you switched computers (or computer to a router) you needed to turn off the modem for 30 mintues. I think this signaled their server that it was OK to work with a new MAC address.



Anyway, it sounds as if you can connect to the modem if you connect one computer to the modem. It also sounds as if you can connect to the airport base station with one computer.



I think you need to separate the issue of connecting to the modem with the issue of connecting to base station.



The settings you selected for connecting the base station to the modem sound correct.



I've always used our routers or base station as a DHCP server. In looking through the manual I don't see a way to set fixed IP addresses. It does talk about sharing a range of addresses but it sounds as if those should be set by the ISP, not that you can decide on them locally.



Do you really need to stick with those particular addresses? I've found that I usually get the same address when I connect to the same router.



If you set the base station to be a DHCP server and you set your two computers to connect via DHCP are they each properly assigned an IP address? Can they then see each other on the LAN? If so, that you can isolate on the problem to one of connecting the base station to the modem.



One other thing, if you ever get down to Tokyo you could drop by the Apple Ginza store and ask them for help. You might also try asking your ISP for help. I was using the JENS AT&T service. It was a little hard to get phone help in English but they could communicate OK by email.

Actually my ADSL modem has a built in router.

I have to use the ADSL modems built in router if I want to use the IP-phone. I'd like to just turn off the whole thing and have the AirPort basestation take care of all of the stuff. I had it that way before I got the IP-phone, just having the modem powered on with no settings, and the AirPort basestation would logon to my provider.
