unable to access internet thru router and dsl modem

I have 25-networked/workgrouped computers(working thru Linksys Switch)that are unable to access Internet thru the Router(Linksys) and DSL Modem(Westell 2200 from Verizon, both recently added...) Im sure I configured both devices correctly, PPOE as requested from Verizon. If i DIRECTLY hook a computer up to the ethernet port on the back of the router, it works fine, but if i go go from the Linksys Switch to the router, its unable to access the Internet.  Also, and this is a variable I'm not sure How it can effect things, connected to one of the workgroups is a machine running MS 2003 server OS.  I think this doles out addressing and im not sure if this is preventing, for whatever reason, workstations seeing the router/dsl to be able get to the Net.

Thanks Guys...

    The ethernet port on the back of the router is simply a switch also.  If all is well then all ports, router and switch, should yield the same results.  Since you cannot access the internet through the switch but can through the ethernet ports on the router then the problems is with the switch itself.

    I'm not sure what specific models your using but some Linksys routers have an uplink port that needs to be used.  If the switch is newer IT should be autosensing and shouldn't matter.

    If your server is offering DHCP, which it shouldn't be by default, you will need to address that issue.  The bottom line is really checking what IP addresses the clients are receiving when connected to the switch.  Start -> Run -> cmd -> ipconfig

    Thanks, it seems that the server in question is in fact contending with router assigning addresses.  DHCP was turned on the server.  Thanks again for your help!
