Hey guys, I have run into this issue a few times and am trying to gather information on the most reasonably priced hardware to do what I want. At a few small local hotels and businesses that I take care of they would like to offer Wireless to their guests (in the lobby for example) using their existing DSL internet connections that they currently use behind the desk. Most of these small businesses cannot afford two internet connections or a complicated dual IP modem / service from their current ISPs. The idea here is to, with hardware, separate the public and private networks so guests using the free wifi cannot access the business machines on the private side. In the distant past I remember having daisy chained two routers such that the private network runs off the original broadband modem/router and the public network runs off the second router which has its WAN port connected to the modem/router's lan ports. Here are the problems I have had trying to recreate this scenario..
1. At two different times I tried using two different brand routers as the secondary router for the public side but both times I could never get the WAN port of the secondary router to acquire and IP address from the primary private modem/rotuer. I have the secondary router setup to Dynamically acquire an IP on it's WAN port (which is connected to the LAN port of the primary modem/router) but it never acquires an IP, even though the DHCP server on the primary modem/router is on and giving IPs to other PCs just fine. Yes, i've tried both a regular and crossover cable, nothing helps. I even tried to put in info and setup the secondary router as if it were using a Static IP on the WAN port, but that never works out..
2. On one other occasion, I setup a newer Dlink router as the secondary router, it did acquire an IP on it's WAN port from the primary modem/router and would go online fine, but it did not provide the public / private network separation like it was supposed to. Computers running off the private modem/router and the secondary dlink router could still file share and see each other on the work. Just what I was trying to prevent! It still allowed them to share files even if I setup the second routers DHCP server to give out IPs of a different ip type..
3. In the past I have also used a Dlink DSA-3100 public/private gateway that is specifically designed to perform this task but the problem is that they are nearly $500 and I believe they are discontinued as they are hard to find in stock anywhere. If i could find a comparable product that would work, but if I could accomplish the same thing with a daisy chained router for under $100 that would be better.
I know I have done this with two routers in the past, I just forget what brand/model worked for the secondary router. Most routers I have been trying now, for some reason just don't acquire an IP from the WAN port when its connected to the first primary modem/router's lan port. Does anyone know of a brand/model router that will for sure acquire and IP on its WAN port from another routers lan port? Anyone know of another way to do what I want in a cost effective manner? Thanks!
