We need help with multiple IPs and 802.11b AP [ip subnet] [dhcp requests]

Q: I have 5 IP addresses from the PacBell DSL Business improved. I need to wirelessly distribute IP addresses to 5 hosts. At present, the equipment is an ADSL splitter Caymen “modem” and a D-Link DWL-1000AP. The D-Link is only one access point, no DHCP support, but it will pass where there is a DHCP server running on the network. Anyway, the point is to avoid DHCP altogether.

So the question is . Can I use a static IP, subnet and gateway to each of the hosts of this equipment, and they all run through the AP? Should I subnet and gateway of the ISP info?


Re:My bad – I was inferring you will be using the public IPs from the provider for each of the computers (w/o NAT exposed to the Net). If you are going to be using the NAT function on the DLINK, then you should be fine.

The SMC provides NAT, which of course isn't really security as the router doesn't provide SPI. Can you suggest an additional economical security solution for a SOHO environment.


Re:FWIW – you got no network security set up, as you're connecting directly to the ISP. WEP is meant to protect communications from your AP to the computers. You're still open to attack from people going through the ISP's modem.

Re:Thanks for the help. I figured that the AP essentially a wireless hub, but the damn config was throwing me for a loop.

I think the main problem was figuring out the D-Link interface; it's a bear. There's new firmware adds web-based config and 128-bit WEP (vs. 40-bit out-of-box), so anyone using this AP should definately upgrade right off the bat.

We've determined that the multiple IPs (enhanced DSL) are overkill for the implimentation, since there is no plans for setting up VPN, hosting, or heavy-duty routers in this p2p environment. We've opted for basic PPPoE DSL and an SMC Barricade SMC7004AWBR.


Re:simply add them manually in the network control panel

Re:An 802.11b Access Point is a wireless hub. Just think of it like that because that is what it is. The AP needs to get on the backbone somehow so you can use a patch cable, probably a crossover from the dsl modem directly or if the modem is attached to a hub or switch just attach the AP to that hub or switch. Obviously if you do not have a DHCP server then you will have to manually add your IP info on your clients nodes.
