Will residents private lan interfere with my business's

[brianleedy00]

I have installed an 802.11b network for the company I work for. We used it to connect 2 of our offices. But to do so I had to hope it in 2 times on ridge tops. So I am on a tower with an omni directional Radio Waves ant. We are primarly using the wireless to connect the remote office to our Highspeed Internet T1. Well I realize I have the best tower sight in town and also realize that I'm not anywhere near using all of the bandwidth of my T1. And I want to provide to the public. Our 2 offices are using a private network. (192.168.1.???) (255.255.255.0) I have a block of public IP ADDRESSES provided by SPRINT. I know if I sign up residential customers I'm going to just give them a public IP address. ( I THINK) but what if they want to network computers at their homes. and they use the same network (192.168.1.???) (255.255.255.0) this will put them on my network (CORRECT)??
I don't want that. How do I get around this? So that they can't get on my companies private network. And also, if customer John Doe signs up and I give him a public Ip address of (148.78.255.200) and he uses that as a gateway for the rest of the computers at his house but puts the other computers on a private network. And his next door neighbor does the same will their private networks talk?

I'm really not all that smart when it comes to this.

Please reply with any info you can. I'll greatly appreciate it.

Thanks

I would use an Access Point that has NAT and DHCP functionality. So you can put the public on their own network and pump the connections to your router through NAT.

So the Access Point has one of your Sprint IP addresses and the public are on a scheme that you can choose. Sprint will just see the Access Point with many connections.
