One DSL connection - want to use two routers - one to provide wireless connectivity - can I do it?

I have a hotel with DSL service.
I have two routers, one which serves as a hub for my LAN.
I want to use another router to provide wireless connectivity for my guests.
I want that router to use a different IP than my LAN, so guests can't get on the lan.

Can I set one up as an access point using a different IP system?

It's possible to do this, you'll have to configure the PCs on your LAN with firewall software to restrict the range of IP addresses that can connect to them (this would not stop IP spoofing, but combined with user ID and password security, would be sufficient.)   Here's what you'll need to do.

1)   Connect your wired router to the DSL modem, have it configured to give out addresses via DHCP.  For example, if the router address is 192.168.0.1, have it assign addresses from 192.168.0.100 through 120.
2)   Configure the wireless router to assign addresses via DHCP, using a different IP address range, e.g .172.16.0.x.   Assign the router a static address in the 192.168.0.1xx range configured on the wired router (e.g. 192.168.0.120).
3)   If you have 10 PCs in the hotel, for example, assign addresses to them ranging from 192.168.0.100 to 192.168.0.109.
4)   Configure the firewall software on each PC to recognize only addresses from 192.168.0.100 through 109 as trusted addresses.   This will prevent traffic from the wireless router, at address 120, from being recognized as trusted, keeping guests off your PCs.

connect your DSL modem to a hub.  connect your two routers to the hub.  each router needs to be configured to run on a different subnet, but both routers point to the DSL modem as the default gateway.

by the way, you will need 2 static IP's in order to do this.  each router will need its own IP

actually, i take back my last statement.  you would only need 2 static IP's if you were doing something like VPN.  you can use the config i suggested without the static IPs

I can get connectivity - if I set router b to 172.16.151
(router A is 172.16.1.1) but it allows browsing of my LAN.

If I change router b to 172.16.2.1 and turn on dhcp,
and connect to wan port - the status shows I am connected to 172.16.1.1 and evrything looks good, but I can't get out to the Internet.

I got the connection working - however - it seems as though unless I purchase another IP from Verizon - everyone can see anything they want.

How come the system won't allow split points for this question?
