Re: D-link ADSL modem only works with one Mac?
Thanks for the suggestion Onno - intriguing option. The down-side of the cheap option is of course that the host Mac would need to be on all the time and if it died or was re-started, the other Macs would lose connectivity. As such, I think Dad will probably go for the DSL-500 or 504 from Westnet and have a more robust, secure option. Thanks everyone. ciao -Mart At 5:55 PM +0800 2/9/03, Onno Benschop wrote: On Tue, 2003-09-02 at 17:35, Martin Hill wrote: Oops - Checking the specs, the DSL-302G only supports 2 computers *sigh* Okay, so it's the DSL-504 with the superfluous built-in 4-port hub we'll have to get for over twice the price. *double sigh* No. Again.

Re: D-link ADSL modem only works with one Mac?
Any thoughts anyone? Umm... The DSL-300 modem specs on the D-Link web site make no mention of DHCP or NAT support (it is, after all, equivalent to a modem, and probably designed for use by a single PC whose MAC address it binds to). The DSL-500 router specs do offer DHCP and NAT (which is what I use on my LAN). Good luck, Shay -- === Shay Telfer Perth, Western Australia Technomancer Join Team Sungroper, race the Opinions for hire [POQ] 2003 World Solar Challenge [EMAIL PROTECTED] fnord http://sungroper.asn.au/
Re: D-link ADSL modem only works with one Mac?
More of a question than an answer, but then it may lead to the answer ! Question: When there are multiple macs on the connection they need individual Identification... How else are they going to receive there part of the stream ? So how is the individual identity applied DHCP server itself would ( I imagine ) need to identify the individual Macs Bob On 2/9/03 4:18 PM, Martin Hill [EMAIL PROTECTED] wrote: G'day everyone, Summary: Anyone know what may be causing a D-Link DSL300 ethernet modem to only allow one Mac to connect through it to the internet? Westnet support indicates it should work (in fact the guy I talked to has the same modem and shares his connection to the other PCs in his house). Our Westnet account is supposed to allow multiple computers sharing the one ADSL account. Details: I've just set up my Dad's new D-Link DSL300 ethernet modem packaged with his new Westnet ADSL account and have successfully connected to the net with the Mac that initially sets up the ADSL modem (termed the Manager PC). However, whenever I then plug the ADSL ethernet modem into his 4 port hub to allow 2 other Macs to share the internet connection, only the original (Manager PC) Mac is able to get a DHCP lease from the modem and connect successfully. The other Macs act as if there is no DHCP server on the LAN. The 4-port hub is routing Appletalk between all the Macs as they see each other and the printers over the LAN ok, but they can't get an IP address. If I directly connect one of these other two Macs straight into the D-link modem (no hub) it still doesn't work. However, if I delete the first Mac from the Account Authorisation config webpage of the D-Link and then plug the modem into one of the other Macs and get that Mac to set up the connection (and thus become the Manager PC) it will then work on this new Mac but not the others. Manually entering IP addresses on the other Macs (instead of using DHCP) hasn't worked either. I tried my Powerbook which uses DHCP here at work and at my place with an airport hub and it also can't get a DHCP lease from the ADSL modem unless I use it as the Manager PC. I'm suspecting something is wrong with DHCP server of the D-Link ADSL modem. Any thoughts anyone? Thank -Mart

Re: D-link ADSL modem only works with one Mac?
Thanks for the feedback Shay and Bob. Westnet has just gotten back to me indicating the DSL-300+ Gen2 indeed does have a DHCP server built-in (as the docs indicated) *but* it will only assign an IP address to one computer. This modem needs to be configured in bridge mode, the connection established using RASPPPoE software and connection sharing software is needed to share the connection to more then one computer. Short of buying an extra ethernet NIC which wouldn't fit in the iMac or the iBook, I can't see a way to turn on Internet sharing using this modem. I'm awaiting confirmation that it indeed won't do the trick in which case we'll see about upgrading to the DSL-302G which does natively support sharing. -Mart At 4:37 PM +0800 2/9/03, Shay Telfer wrote: Any thoughts anyone?
