One of the requests which is being refused is a zone transfer request from

Quoting ipfw(8):
Hi folks,
I already found the mistake of my ruleset sequence on my box, for ex:
${fwcmd} add 30 fwd ${ipproxy},${portproxy} tcp from ${ipclproxy} to
any dst-port ${porthttp} in via ${ifint0}
${fwcmd} add 52 pipe 2 ip from any to ${ipclient} via ${ifint0}
${fwcmd} add 53 pipe 3 ip from ${ipclient
I have a fairly restrictive firewall but I wanted to open a hole for ping and
traceroute - both outbound from a NATed LAN as well as inbound to the boundary
FreeBSD machine. The magic sauce turned out to be:
ipfw add allow icmp from any to any icmptypes 0,3,4,8,11,12
The other insight here

I have a fairly restrictive ipfw setup on a FBSD 8.2-STABLE machine.
Pings were not getting through so I added this near the top
of the rule set:
#
# Allow icmp

${FWCMD} add allow icmp from any to any

RIght - if you're just protecting a single host, for example, your
ruleset might be something like
ipfw add 1000 allow ip fr
n as well. Suppose you wanted to
permit outbound TCP connections using stateful rules. If em0 is the
outside interface of your firewall
If you're using stateful rules, you would do something like this:
ipfw add 1000 check-state
ipfw add 2500 allow tcp from any to any out xmit em0 setup keep-state

I am attempting to set up a firewall using IPFW with a stateful
behavior.
While I have investigated how to set up these rules, I have run into
conflicting opinions as to whether to all or deny "established"
behavior.
EXAMPLE: (preceded by a "checkstate" rule)
allow
What's the limit of entries for table of ipfw?
Thanks in advance.
