Notes from when I used ar0176e0/1 to be a temporary, "We're down for Maintenance",
web server.

1)  Had to change the 
        Rule Number     Rule Name      Rule Description
        ===========     =========      =========================
          512           httpNon        TCP in port 80 nonsecure  
          513           httpsNon       TCP in port 443 nonsecure 
    Firewall rules to allow packets to travel outbound from us.
    The rules used to be

Also added 2 more rules for tcp-ack, both ports 80 (rule 531) & 443 (rule 532).

Added new rules to 504 service.  I.E. made sure "Rule Objects" field was
inbound-512 inbound-513 inbound-531 inbound-532
instead of just inbound-512 inbound-513.

Then you back out to "Filters" menu,
select "Control Filter Status",
select "Activation",
select "Activate / Update".
