Deze howto gaat net als deel 1 over het beveiligen van je netwerk met OpenBSD als router / firewall. Deze keer bespreekt de schrijver de nieuwe packet filter PF.
[quote]As you can see‚ the names of the configuration files have changed as well: packet filtering rules are now stored in the pf.conf file located in the /etc directory. The network address translation rules are stored in the nat.conf file located in the same directory. When pfctl complains about syntax errors‚ use the -v option to display the rules as they are processed by pfctl. For example‚ when the packet filtering rules contain errors‚ use pfctl –v –R /etc/pf.conf | less to browse the output and locate lines with errors; then edit the configuration file and try uploading the new rules again.
