IP Chains shouldn't be required unless you're doing IP Masquerading. 
Straight TCP/IP network stuff should just work.  Standard questions to
be asked, just in case...
Nameservers set correctly in /etc/resolv.conf?
Does the machine dual-boot to Windows?  If so, does Windows connect
okay?
Is the LAN card functioning properly?  (IRQ's, driver, etc.)
