is it just me, but i am looking at creating a firewall rule to block everyone except 3 or 4 specific ip addresses.
the rule is basically (assuming 1.1.1.* = a valid external ip address)
when incoming request matches
(ip.src ne 220.127.116.11) or (ip.src ne 18.104.22.168) or (ip.src ne 22.214.171.124) or (ip.src ne 126.96.36.199)
then choose option Block
