Default Using Multiple ISPs on OBSD 4.9

Greetings to all!

I have read the FAQ PF: Address Pools and Load Balance in an effort to under what I must do to get Ultra1 to use multiple ISPs for failover/balancing. So far is a no go.

I tried to follow the same example to make it easier.

AT&T            Covad 
    |   2701HGV-B        Zyxel 600
    |                            |
    |                            |
   adj.                        adj.
  router                    router   
    |                             |
    |                             |
    |                             |
    |                             |
    |                             |
|  hme0               hme1       |
|     |
|             Ultra1                 |
|     gateway/firewall           |
|                                      |
|         hme2                      |
|                |
      internal lan
I am able to access the net from the firewall but unable to surf the net
from a Windows test machine setup to hit the as its gateway. The PC is able to ping its it's IP and it's default gateway firewall is not able to ping the test machine.

I have enabled routing and setup the PF rules as the example given on OpenBSD FAQs on load balancing Outgoing Traffic.

Do I need to add static routes to the hme2 interface? I'm sure you can tell of my limited knowledge on the subject.Please advise if I need to provide more info. Your assistance and help is greatly appreciated.

Once this issue is resolved how can I test if the traffic is flowing between interfaces?

Thank you in advance.
