I've been asked to set-up an open (free Hot Spot) wireless access point at our community pool area. Currently they just have a cable modem providing internet access to a single PC. No router, no wireless, just directly into PC where they use a software firewall. The reason for using Open-Mesh is to offer a splash screen with disclaimers.
As the first test, I was wondering if I could simply go from the ISP modem, to a switch that would offer access to the PC and the wireless access point. I am planning on using a EOC-2610 Engenius Access point flashed with Open-Mesh. From what I have read, you simply add the MAC address to their dashboard.
ISP Internet-----Cable Modem---------4 port switch--------PC
Will this work or do I need to purchase a wireless router then flash it with Open-Mesh along with the Access Point. Although I have set-up standard internal networks before, this is the first Hot Spot so any information on setting this up is greatly appreciated. I've tested the Access Point on a network which has a router and I can connect, but Open-Mesh does not see the Access Point. I am assuming that is because it is behind the firewall which I guess brings up another question. If I do not have a router, will I run into a problem that I have multiple devices without a router which normally provides the DHCP server or does the cable modem also offer that service?
