newbie: cisco vlan newbie question

Hi,

I have a router 1721 router with 2 WAN Interface Cards (WICs) and 1 buildin
fastethernet:

WIC-1ENET -> USED FOR INTERNET CONNECTIONS:
1) Ethernet0 = is connected to a TV cable modem (for internet browsing
etc..) and gets it's ip address from a dhcp server

BUILDIN FASTETHERNET:
2) fastethernet0 = 172.16.43.1
This ethernet is connected to a third-party switch (from TRENDNET) where I
have my home network connected: 172.16.43.0 / 255.255.255.0
All PCs get there ip address from a dhcp server running on the cisco router.

I have bought a WIC-4ESW Cisco 4-Port Fast Ethernet Switch WAN Interface
Card
Which are:
3) fastethernet1
4) fastethernet2
5) fastethernet3
6) fastethernet4

I would like to connect a PC to fastethernet1 (from WIC-4ESW ) with an ip
address of 172.16.1.1
a) The pc (with IP 172.16.1.1) should be able to ping any host on the
internet
b) The pc (with IP 172.16.1.1) should be able to ping any host on the
network 172.16.43.0
c) The network 172.16.43.0 should be able to ping the 172.16.1.1 host

How do I have to configure the vlan stuff etc....?
Unfortunately I have no experience and no idea how to do a vlan
configuration.
So "any" help (links, books etc) would be greatly appreciated.

Thanks in advance

 

And how do VLANs figure into this?????

 

Hi, VLAN configuration is not needed in your scenario.

Hi,
Thx for answering
When I try to give the port an ip address, I get:

ip address 172.16.1.1 255.255.255.0
% IP addresses may not be configured on L2 links.

So I think I need to configure vlans?!

% IP addresses may not be configured on L2 links.
