router on a stick

i was tasked to implement internet access in a hotel

due to budget constraints this can only be done with a 1721 router and 6 2900 series xl switches.

1) the router should provide ip address for all host

2) host should not be able to see each other

i am posting my config for the router and switches.

problem number

clients can not obtain ip address therfore can not surf the web

can anyone tell me what i am doing wrong?

thank you

Re: router on a stick

In my experience setting up a router to act as a DHCP server I have always used the "ip dhcp excluded-address" command. I have included a simple config I did to serve up addresses to my lab. I believe this should take care of your problem.

--------

ip dhcp excluded-address xx.xx.xx.65 xx.xx.xx.114

!

ip dhcp pool PRODRAIL

network xx.xx.xx.64 255.255.255.192

default-router xx.xx.xx.65

domain-name mylab.com.

dns-server xx.xx.xx.xx
