Need Help setting up router-on-a-stick with a Cat-3524XL

I have a cisco 2651 router and a catalyst 3524XL switch. I am trying to setup the router to act as a router-on-a-stick, using dot1q encapsulation. I want to run 2 vlans currently, one using the IP of the router, and the other using another of my static IPs. I want to host a webserver and mail server on one VLAN and have another vlan for workstations. Any configuration help is greatly appreciated. I have done this before, but with a 3550 switch (which doesn't even need router-on-a-stick) and I can't seem to remember how to set it up again. The IOS on the switch is also a very old version of IOS, 12.0.5. Any help is greatly appreciated. Thanks again.

Grrrrrrrreat. With that old IOS, I have only one question: Does your router have FastEthernet connection?

If the answer is NO, then you can't go any further.

Actually, that's the latest IOS on such switch.

On the 3524, create the L2 Vlans;

#vlan database

(vlan)#vlan 2 name web_and_mail

(vlan)#vlan 3 name workstation_lan

(vlan)#exit

interface fx/x

description Cisco 2651 Router

switchport trunk encapsulation dot1q

switchport mode trunk

switchport trunk native vlan 3

On the Cisco 2651 router:

interface fx/x

description connection to Catalyst 3524xl

interface fx/x.2

description Web_and_Mail

encapsulation dot1q 2

ip address x.x.x.x y.y.y.y

interface fx/x.3

description workstation_lan

encapsulation dot1q 3 native

ip address y.y.y.y x.x.x.x
