WAN Failover with 2821

Have a Cisco 2821 that currently has the 4esw-Hwic.  There is currently a fiber/ethernet internet connection on it, want to add an additional Internet connection and have it failover, preferably to specific Lan networks, But I'm not sure it's possible with the current hardware. Won't the router always see the 4esw ports as up?  Can this be done?

heres the current interface list

nterface                  IP-Address      OK? Method Status                Protocol

GigabitEthernet0/0         WAN IP   YES NVRAM  up                    up

GigabitEthernet0/1         LAN IP  YES NVRAM  up                    up

FastEthernet0/0/0          unassigned      YES unset  up                    down

FastEthernet0/0/1          unassigned      YES unset  up                    down

FastEthernet0/0/2          unassigned      YES unset  up                    down

FastEthernet0/0/3          unassigned      YES unset  up                    up

Vlan1                      unassigned      YES NVRAM  up                    down

Vlan2                      Assigned to fa0/0/2     YES NVRAM  up                    up

Yes, it ispossible.

If you are not sure how to configure it, engage a reputable consultat or certified Cisco partner, to avoid a spending a lot of time learning things to be used once.

I'd like to learn how to do it, as to gain an understanding on how to do it, if I always paid someone to do something I couldn't I'd never learn how to do anything..lol, I'd be willing to pay someone to guide me through the configuration, if they want to send their contact info

For a basic Failover scenario, check this document:

http://docwiki.cisco.com/wiki/NAT_failover_with_DUAL_ISP_on_a_router_Configuration_Example

For implementing PBR (so that specific vlans chose specific ISP while trying to access Internet) check the following documnet:

Hope it helps you in getting started
