Home network questions with Router/Firewall

Bacically I'm a UNIX hardware guy and don't perform too many admin networking tasks, but I'm trying to get both my Linux (Debian) box and UNIX box (HP-UX) up on the internet from my home network.  Currently I have a cable modem using DHCP from my ISP (they won't give me a static IP) connected to a Netgear FVS318 router/firewall with 3 machines hanging off of it (Win2k box, Linux, and HP-UX).  The Win2k machine works fine on the net, but I need some help configuring the other two.  I currently don't have a DNS server on my home network, but could set-up one of my boxes to do it if needed.  I'm not all that competant with DNS.  I have set-up my default gateway on the UNIX box as 192.168.0.1 (router IP).  When I do an nslookup on the box I get "Can't find server name for address 192.168.0.0: None-existant domain" and "Default servers are not available Using /etc/hosts on: <hostname>.  I also get the hostname, address, and aliases.  I'm assuming that the aliases should be set to the domain of my ISP, but correct me if I'm wrong.  My router does support NAT.  Doing a vi on my /etc/resolv.conf yeilds the domanin (of my ISP) and the nameserver (default gateway of my router).  I can ping via IP on my network, but not via hostname.  I know I have to create host files containing all my hosts on each machine but I don't remember how to change the DNS search order.  If anyone has any suggestions, please let me know.  Thanks.

Surely the nameserver in /etc/resolv.conf should be the DNS server of your ISP, not the gateway (your router)?

If you want a quick easy fix go pick up a Linksys router.  It will pick up your assigned ip and translate it to your internal LAN.  Also has a firewall built in.  It's easy to manage (all done through web browser).  Just keep in mind that it's a Linksys product not a PIX firewall!!

To finalize, I had to change my DNS search order on the UNIX box and make a fully qualified host name for it.  After that I stumbled through SAMBA and got it working also.  Thanks for the responses.
