Looking for info re. programming NAT, VLAN

I'm trying to program a 1711 Cisco router for small office, home LAN using Cable broadband cable modem.  I'm looking for info or docs about programming for NAT.

The router has a 4 port switchcard (4esw)

The way I understand it, I'll program Fastethernet port  0 (F0) to connect to cable modem, using dhcp and NAT outside.

F1 -F4 will run via VLAN as NAT inside.  My problem is that I'm fuzzy on details.

Do I also need to set up a default route ?

If you can point me in the right direction, I would appreciate it.

Thanks!

If You configure outside interface to get ip addr from DHCP server, You no need to set default gateway.

How to configure NAT look at the CISCO cookbook or http://www.cisco.com/en/US/tech/tk648/tk361/technologies_tech_note09186a0080094e77.shtml

About VLANs: it depends on network topology (one trunk link to switch or tagged interfaces in 2-3-4 networks).

However, use search on cisco.com. It's better solution )
