Kernel with ALTQ support for PF

If you build a router with PF and ALTQ support you will need these options added to your Kernel. Copy GENERIC file to a new file, for example ROUTER (GENERIC file is located in /usr/src/sys/i386/conf) then edit and add the following options: # -------- append this to ROUTER kernel configuration file ------------- # used for bridge support, device polling and ipstealth protection options BRIDGE options DEVICE_POLLING options IPSTEALTH # tuning options MAXFILES=8192 options SYSVMSG # ALTQ support in kernel options ALTQ_CBQ options ALTQ_RED options ALTQ_RIO options ALTQ_HFSC options ALTQ_PRIQ # pf (OpenBSD's Packet filter) support in FreeBSD kernel device mem device pf device pflog device pfsync # ------------------------- end of ROUTER file --------------------------- As you see not all options are for PF and ALTQ support. There are some other options that helps when you build a router (like DEVICE_POLLING) support. This kernel configuration file also supports BRIDGE mode, for building a BRIDGE.
