Keep in mind the ACK packets originating on the the BSD machine will still have a TTL of 64 if that is what is defined by your “sysctl net. Here are some situations you might use each type of service for. Ttl” or if you do not set that directive at all.

The default policy is to drop packets. The log level is set to “Urgent” by default. The pf rule sets are going to be required to be in order of options, normalization, queueing, translation, filtering. We are going to log on the external interface and the state policy is interface bound. Misc OptionsThis is a list of default behaviors for pf. The man page of pf has a very good description of all of the miscellaneous options used here. Os fingerprint file is defined and we are going to ask pf _not_ to try to optimize the rules as they are already in a good order.

He is explaining the processes Pf uses to determine if the packet coming in matches a state we have, a state needs to be created for a pass/match rule or if Pf needs to drop the packet. We have reformatted text for readability. This is a response on the OpenBSD Mailing list from Henning Brauer.

This rule expands to say that any packet the internal interface sees that is not allowed by any other rule will be blocked. The directive “return” says to send a “reset” packet back to the ip instead of just dropping the packet out right. The same applies to the protocol that is not defined, pf sees this and assumes you mean “tcp, udp and icmp” packets. Notice this rule does not have a “in” or “out” entry. This is because if it is not specified then pf automatically assumes that you mean “in and out”.

The value actually refers to the maximum amount of data a segment can hold and does not include the TCP headers. We need to point out the name maximum segment size is in fact misleading. So if the MSS is 100, the actual maximum segment size _could_ be 120 (for a regular TCP header) or larger (if the segment includes TCP options).

The theory being that no one should be connecting to our firewall on any port we are not running a service on. Our anti-scanner using Pf will look for access to ports not used for any local services. Once they know what ports are open they can deduce what services are being run. A scanner is a remote computer who accesses multiple ports on your machine to see which ones are open. Can I automatically block port scanners like Nmap, Superscan and Unicornscan on my firewall.

La commande suivante permet de créer une route: route add -net 172.

However, one problem is that the routing information will not persist if you reboot your FreeBSD machine. The above example is perfect for configuring a static route on a running system. The way to handle the addition of a static route is to put it in your /etc/rc.
